4x - (2x + 6) = 8x - 12 distribute -
4x-2x-6=8x-12 combine like terms
2x-6=8x-12 add 12 to each side
2x+6=8x subtract 2x from each side
6=6x divide by 6
1=x or
x=1

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

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