multiply out
2x - 2 = 7x +8 +28x +8
regroup on each side
2x - 2 = 35x + 16
subtract 2x from each side
- 2 = 33x +16
subtract 16 from each side
-18 = 33x
x = -18/33
hope this helps!

2(x-1) = 7x + 8-4(-7x-2)
2x-2 = 7x +8 +28x + 8
2x-2 = 35x + 16
-33x = 18
x = -18/33

2x - 2 = 7x + 8 + 28x + 8
2x - 2 = 35x + 16
- 18 = 33x
x = - 18 / 33
x = - 6 / 11

you need to trnaspose the x's and the nonx's on both sides.
2x-7x-28x = 8 + 8 + 2
the answer is negative 18 over 33.

ok, i assume you are solving for x so
2x-2=7x+8+28x+8
33x=-18
x= -18/33
