Can you answere it?
I can.

I can.
well, x = "nothing" but the answer to the equation could be "26" or "7=19".
not possible to solve.
first get the variables all on one side if i remember right, but you subtract x from one side and then the other, there is no more X, just 7=19, or you could do that later and add 7 to both sides which leaves you with "x=26+x", then subtract an x from both sides then that leaves you with the answer 26, but not x=26 because of the fact X no longer lives in this equation.
Soo, where is my cookie?

x7= 19+x
no solution :icon_thumbsup

x7= 19+x
no solution :icon_thumbsup
Yes there is.
What is the value of X?

this is what i come up with:
Simplifying
x + 7 = x + 19
Reorder the terms:
7 + x = x + 19
Reorder the terms:
7 + x = 19 + x
Add '1x' to each side of the equation.
7 + x + 1x = 19 + x + 1x
Combine like terms: x + 1x = 0
7 + 0 = 19 + x + 1x
7 = 19 + x + 1x
Combine like terms: x + 1x = 0
7 = 19 + 0
7 = 19
Solving
7 = 19
The left and right sides are not equal, therefore there is no solution.

Yes both sides ARE equal.
The statement SAYS they are.
The question is therefore ...what is the value of X.
Like most people your just trying too hard and are over looking the simple way to solve the problem while the answere is right in front of you with neon lights pointing it out...so to speak.
I see people do this all the time when trying to make a cheat work or bypass an anticheat system.
Just stop thinking so hard.
The answere is very simple!
With a simple puzzle like this those schooled in "higher" ways of working things out almost always fail becuase they are trying to use everything they have been taught to figuare it out.
That is the wrong way to think.
It is like training for self protection...follow the basics and the body does without the mind stopping to think about it.
Relax your mind and let it go back to the basics.
Put yourself back on autopilot (yes I flew aircraft and have a licence...still).

Moved from the RIB Section and the Hmmmmmmmmmmm Totpic to here....for you "brainiacs" to solve.

x = 6?

LOL dude i even google equation solver'd it. maybe in computer program world theres an answer but im pretty sure in the math game theres no solution do to the givin rules but lol maybe i am missing the point :arr arr

The equation is simplified into x^2 = 26. So x = the square root of 26. Which cannot be simplified any and according to google calculator is 5.09901951.
Edit i just realized that's a positive X, not negative. Ha ha, guess i'm stupid too :icon_laugh
So all that i just typed is wrong... :icon_rolleyes2

I wonder how long I should let people work on this befor I tell them what "X" is?

I wonder how long I should let people work on this befor I tell them what "X" is?
How long did it took before you found it?

As soon as I saw it.
It is the only possible way for the statment to be correct and it is not a natural number.

i get it, x = Y
where y = whatever the fuck i want it to.
or X just =x and leave it at that.

It is soooooooo simple.
If "X" can have natural number added/subtracted and still remain equal...then the same will hold true if you divied/multiply...therefor "X" can only be one thing in math.
I hated math in school and the reason I last did programming back in 1984 was becuase at the time it was almost pure math and ATARI BASIC had just came out that made it easyer.
You C* guys have it easy.

dude fuckin make sense of it then already im stickin to my answer of 7=19 [not equal to] therefore x is undefined or no solution at least by correctly using the right procedure. so explain tcrew

You C* guys have it easy.
lol dont they just

i'd rather have cream cake or a nice forrest gateugh .. personally lol
i just posted this and it says ive edited it ( i have now ) but i didnt , server in trouble again?

No problems buddy.
BTW...you do see the answere to the vaule of "X" right?
PM me if you know it or if even you are stumped...it is so easy smart people overlook it.
I might let these younger guys have the answere this Sunday...or not.

dude i was the shit in my math class and im not such a hacker but im extremely profficient with computers and im 21! my answer stands. final answer = no solution x is undefined 7 does not equal 19 :icon_teehee

Well your wrong becuase "X" does have a value and it makes the statement correct.
It is really not that hard of a puzzle!
I am going to invite both Doolittle and JBOY (who defaced the main TKC page a few days ago) into this. They claim to be smart and I know that at least Mr.D has a computer science diploma....but I doubt even they can figure this out...they may also "think too hard".

are you 1 trying 1 to say that u add 1 to each side cs that doesnt work either

are you 1 trying 1 to say that u add 1 to each side cs that doesnt work either
No.
I already said that the math statement is correct and that the value of "X" is what you need to answer....and that value is not a commonly used math function.
So far everyone who has tried to answere and used the most common (and generally correct) math solving skills has totaly overlooked the simple answere.
I PM'ed Doolittle and sent a text msg to JBOY's phone.
Lets see if they want to "school" you guys...if they can even get this correct themselfs that is.
This site has three staff members that are Uni teachers and at LEAST 4 others who also have a Computer Science Diplomas who are long time members (who may not even see this thread)....but the statment is correct and "X" does have a value even if they read this thread and do not see the answere themselfs.

OK...
I was in MSN IM with both Accessed and Symantic and told them the answere.
They are NOT going to post it and are NOT going to give it away in PM/IM.
The point is they see the correct answere and both went...LOL!...when they did.
It is really a very simple and valid function/value/answere.
It is so simple that even most Math Instuctors will overlook it!
Like I said the smarter you are and more trained you are to think works against you becuse you "think" too hard to answere it.

This is an exorcise in general thinking and problem solving.
Many times a programming issue may have you stumped...and the reason is not that you do not have the knowlage needed to solve the issue,but that the way you think with the skills you have studied and mastered that are holding you back from what looks you in your face.
More often than not in real life needs...thinking too hard is a detriment next to standing back with a clear mind and just "feeling" what the answere is and more functional than beating your schooled brains out on it.
The main problem with this puzzle is that it is so simple and transparent.
Step back and not think so hard.
Now what is the value of "X" which makes the statement correct?
The answere is very simple!

I know I'm thinking to hard and I'm trying to simplify anything. Though I can't figure it out.
I have a few idea's but I can't work them out and that SUCKS. (I hate the Windows Calculator).
When I'm at home I'll work something out.
If your on Z let me know. And I'll tell you in what way I'm thinking.

Windows calculator sucks major ass. I tried to use it a couple of days ago and either I missed it or it has no Minus function lol...

It does. It's next to the 3.

Or just enable numlock and use your keypad... :icon_rolleyes2

LOL!
Most calculators are not going to help you with this...in fact I doubt any calculator or a Cray HPC will.

It does. It's next to the 3.
Ah it does. Ty, +1 :D

LOL!

lol im suprised no body has posted the answer yet
its said i edited again lol

I've got it. It's an imaginary number with a symbol that cannot be drawn by a human hand! It's the mark of Chaos! :darkking

OK...I am going to give everyone a big hint:
I can't put the symbol into either MSN IM or ICQ but I can in a forum post.

:icon_magician Is it magic? I think maybe it's a squared number.. I dunno just a guess.

Eh square root, or lowercase i maybe? I dunno, i'm just guessing in the dark here :icon_o_o

infinite 7 does not equal infinite + 19 if infinite is what your thinking

infinite 7 does not equal infinite + 19 if infinite is what your thinking
Close enough.
Your incorrect in your example however.
The value of "X" is "∞"....and no matter what you do to "∞" you can never change it's value.
Now see how simple that math problem was?!

I don't agree with the answer as i said on ICQ.

I don't agree with the answer as i said on ICQ.
I never heard you disagree.
∞ is always ∞,by it's diffenition it can not change.
If you have an ENDLESS thing adding/subtracting/divideing/multiplying or any other interaction still leaves you with ENDLESS.
The only possible exception would be "∞  ∞ =0"...you are still not changeing it's value but you are eleminating it.

graph it for me so i can see it.

graph it for me so i can see it.
Hhehe!
Best I can do is this:
(X7)=(19+X)=X=∞

isn't infinity undefined? so if x = infinity then x = undefined?
Pwnd :D

isn't infinity undefined? so if x = infinity then x = undefined?
Pwnd :D
isn't infinity undefined?
In math it is definded.
Pwnd :D
Yeah...you were.

LOL dude i thought this was a joke but u are serious LOL u made a topic about infinite :icon_teehee hey it beats some of mine though :icon_teehee but dude correct me if im wrong but in math ,right, infinite has no defined value its just 8 [sidewayscouldnt find it on charmap] but like i said infinite + 7 is not equal to infinite 19
i was right!! the answer is no solution! now dive down to your wreckage and recover your valued belongings arrrrr :arr

my point exactly.

I'm with symantic on this. It's impossible to define infinite with a definite value (The words are pretty much opposites) so i'm gonna agree with /\ above me in saying it's undefined. And i'm sure if i put that on my calculus tests last year it would have been marked wrong. . .

From part of the definition from a random page on math:
We may feel some discomfort at the idea that we can remove some of the elements of a set and still have as many as we started with, but this is an artifact of our experience with finite sets (in which removing something means having a smaller set). Infinite sets simply don't behave that way. In fact, this leads us to a definition:
"A set is infinite if we can remove some
of its elements without reducing its size."
Go look it up...

Here is a good math site with more examples of what happens when you add/subtract/divide/muliply useing infinity:
http://tutorial.math.lamar.edu/Classes/CalcI/TypesOfInfinity.aspx

crazy go search for the "string theory" its an example in deeper dimensions time doesnt exist in our dimension it is an illusion we use to measure our lifespan

So?
It has nothing to do with the math problem I started the thread with or the examples of why it is a true statement...nor the question/answere that infenity does have diffinitions in math problems.

Argh more calculus. I hate math. Entirely. :icon_cry2

Well, to be very precise that equation has no solution actually. ∞ is no number, and you can't count with it as if it was a number. ∞ is mostly relevant only when you compute limits of a function.
But you can still think of it as a number and do some sloppy calculations, physicists or engineers like to do it that way. So infinity is a correct solution seen that way, but from a purely mathematical point of view it isn't. :wink2
Infinites are dangerous. Say you have the equation x+2=24. If the above infinite solution is true, "nothing" says you can't add and take a number x+2+∞=24+∞. Then x+∞=∞ and x=0 (or any number, depends on how you do). Which obviously is no good solution.

yeah dude in math that is no solution 7 does not equal 19
but my post was saying that in our dimension infinite[time] is not real and we try to measure it.[time]
so maybe in another dimension like 5 or 6 maybe your equation is easily solvable. but not in ours :icon_sly

What time is, is very difficult to understand. But I like the explanation someone had: time is what's measured by a clock. :smile
However, there are many other things that can be thought of as infinite other than time.
infinite + 7 is not equal to infinite 19
The short answer is, in maths  no. In other sciences  yes.

agreed
http://en.wikipedia.org/wiki/String_theory (http://en.wikipedia.org/wiki/String_theory) but mullah, time is non existant. its only in our heads that all work the same way and agree on a way to measure our lifespan. we made it up, and named it "time"[broken down to the smallest as milliseconds] thats just one way overlooked example of how incredibly intelligent people are. a better name would be "life duration"

time does not exist because chuck norris does not allow it.

No, Chuck Norris DECIDES what time it is.

chuk norris can lick the bottom of the bag

I don't know much about the string theory but it isn't clear if it has anything to do with reality yet.

You don't say?

A computer can understand the infinity as a sort of number and do some limited operations with it (like Z shows), but it's limited to those limited arithmetics. My 68k series calculator can do that :wink2

Well E=MC2 is mostly not made of numbers but the statment is correct.
Bad example for what I am trying to say but my back hurts and I need sleep.

this is what i come up with:
Simplifying
x + 7 = x + 19
Reorder the terms:
7 + x = x + 19
Reorder the terms:
7 + x = 19 + x
Add '1x' to each side of the equation.
7 + x + 1x = 19 + x + 1x
Combine like terms: x + 1x = 0
7 + 0 = 19 + x + 1x
7 = 19 + x + 1x
Combine like terms: x + 1x = 0
7 = 19 + 0
7 = 19
Solving
7 = 19
The left and right sides are not equal, therefore there is no solution.
LMFAO. You can do this much shorter:
x7=19+x  X
7=19
(not logical)
There is no X which makes this equation possible.
x7 != 19+x  X
7 != 19
QED.

Heh FU i lose my car keys all the time
