9(x + 2) = 3(x - 2)
9x + 18 = 3x - 6
6x = -24
x = -4

5x + 2 = x - 6
4x = -8
x = -2

-2x - 18 = 6(1 - 2x) + 4x
-2x - 18 = 6 - 12x + 4x
-2x - 18 = -8x + 6
6x = 24
x = 4

9(x + 2) = 3(x - 2)
9x + 18 = 3x - 6
3x = -24
x = -24/3 = -8

5x + 2 = x - 6
4x = -8
x = -8/4 = -2

-2x - 18 = 6(1 - 2x) + 4x
-2x - 18 = 6 - 12x + 4x
-2x = 24 - 8x
6x = 24
x = 24/6 = 4
