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

>>23
FAIL.  Invoking higher powers results in creating EXTRANEOUS roots.  EXTRANEOUS means UNNECESSARY, motherfucker!  THERE IS NO S*I*N*G*L*E VALUE OF X THAT SATISFIES THE GIVEN EQUATION!  ±x is NOT a SINGLE value.  You can't ask for ±x change in the fucking grocery store!

You twentysomething collegefreaks just about take the cake.  You learn a mathematical tool, and then spend the next 20 years sticking it into the wrong spots like you're fucking Euler.
