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

>>31

Set a = -b = x and it is. It's ok, I understand that completely elementary algebra can be difficult. To a special needs child.
