y + 2 = y
2 = y - y
2 = 0
( 2 != 0 )
No Solution

Y = Y + 2
Programmers thinking:-
2, 4, 6, 8 etc

I don't consider myself all that great at math, but the sheer level of retardedness in the comments is astounding.

Y is a letter. It cannot be added to a number.
User avatar #13 - Daeiros (01/04/2013) [+] (1 reply)
its easy


i is an imaginary number that is both positive and negative at the same time used when taking the square root of a negative number(which is impossible otherwise, but the need comes up sometimes)

i + 2 = i

because it is simultaneously positive and negative, we can say

-1 + 2 = 1

which is correct
#16 to #13 - anonymous (01/04/2013) [-]
That's not how i works at all. You need to revisit math a little bit. It is the square root of -1, which you had correct, but it is neither negative nor positive. ( i+i is not the same as -1 + 1, nor 1 + 1, or -1 - 1. It is i + i, which is 2i. ) As such, no, you are incorrect. Zero credit. Good day, sir.

actually, Y = ∞...

∞ + 2 = ∞

By the way, that is not a infinity simbol... those are boobs.

I read in the comments that it can't be solved because it's a meaningless equation.    
God damn I wish I was smart enough to understand 						****					 like this.

Imo i would use derivation on this...
first derivation:
f(x) : y+2 = y
f(x)' : 1 = 1
because derivation from y is 1 and derivation from 2 is 0

Problem solved

Except that didn't really solve it, since you didn't even adress the equation itself.
You didn't even try to adress it as an equation. Equations are solved by finding the values of the variable(commonly x, but here it's y) for which both sides are equal.
Functions on the other hand is finding the output for different values of x.
An example of an equation is 2+x=2x with the solution being x=2. Equations can exist for which there is multiple solutions. An example is 1=x^2 with both x=1 and -1 being valid answers
An example of a function is f(x)=3x+7 with there being a different output for each value of x. Functions can exist where certain values of x is invalid. An example is f(x)=1/x with x=0 being invalid.
As a sidenote f(x) means function of x, so for your invalid attempt you should've written f(y).

Also my "attempt" at solving this.
No valid answer.

Surely you would-

y = y-2

#113 to #111 - anonymous (01/04/2013) [-]
you already had the equation
y = y + 2
why would rewriting it as
y = y - 2
be helpful in any way?
User avatar #89 - ithinkimfunny (01/04/2013) [-]
This equation is per definition ******** .
#79 - cheezitman (01/04/2013) [+] (8 replies)
I guess I'm going to have to solve it sometime...

1y+2=1y (the reason I put 1y instead of y is because it is easier to solve)
Subtract 1y from both sides
Divide by 0 on both sides
since you can't divide by zero it isn't possible
so y=Undefined
User avatar #180 - Kabutops (01/05/2013) [-]
uhm...there's no answer for the variable? (90% of gradautes my ass)
User avatar #59 - traveltech (01/04/2013) [-]
y is simply not a real number
#130 - pedobearson (01/04/2013) [-]
That's because this is impossible.

Here we go. This goes for any of the commonly known sets of numbers in mathematics, namely the naturals, integers, rationals, reals and complex. For any element in the set (we'll call it x, and in this example we'll just deal with naturals,) there exists a unique solution to the equation x+a=x=a+x, meaning a is the identity element in respect to addition, or is the additive identity. In all of these sets, the additive identity is 0. That means that x+a=x=a+x is only true when a=0. Since this is a case where a=2, it can no longer hold true for any x in any of the above sets.

TL:DR: There exists no solution.
