6-x=x+6-6
Combine -2x and x to get -x.
6-x=x
Subtract 6 from 6 to get 0.
6-x-x=0
Subtract x from both sides.
6-2x=0
Combine -x and -x to get -2x.
-2x=-6
Subtract 6 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-6}{-2}
Divide both sides by -2.
x=3
Divide -6 by -2 to get 3.
