Combine like terms. 

-7x - 3x = -10x
-10x + 2 = 8x - 8
+10x        +10x

2 = 18x - 8
+8          +8

10 = 18x

18x/18 = 10/18
x = 5/9

If you would like to solve the equation - 7 * x - 3 * x + 2 = 8 * x - 8, you can calculate this using the following steps:

- 7 * x - 3 * x + 2 = 8 * x - 8
- 7 * x - 3 * x - 8 * x = - 8 - 2
- 18 * x = - 10    /(-18)
x = 10 / 18
x = 5/9

The correct result would be 5/9.
