You should be able to solve this.

x - 7 = 19 + x

A famous meme on /b/, well, I just solved it and want the credit.

x-x=26

(x^2)^0.5= a + and - number
For example. -3*-3=9, 3*3=9, therefore 9^0.5 = -3 and 3

+x--x=2x
x-x=26
2x=26
x=+13 and -13

RedCream is right.  x has no real or complex solution.

I don't think "twentysomething collegefreaks" are this stupid.  Some /b/tards are this stupid, while the trolls who pretend to believe this are in it for the lulz.  In short, >>17,21 phails unless s/he is a troll.

By strict mathematical definition, a function can only return a single value.  The term you're looking for is relation.
