-1 + x + -2x = 6 + 2x + -2x

Combine like terms: x + -2x = -1x
-1 + -1x = 6 + 2x + -2x

Combine like terms: 2x + -2x = 0
-1 + -1x = 6 + 0
-1 + -1x = 6

Add '1' to each side of the equation.
-1 + 1 + -1x = 6 + 1

Combine like terms: -1 + 1 = 0
0 + -1x = 6 + 1
-1x = 6 + 1

Combine like terms: 6 + 1 = 7
-1x = 7
