Multiple both sides by 24, that gives you:
4x - 6x = -192
-2x = -192
x = 96

The short approach to answering this problem would be to find the common denominator, which is 12, in this case.
The longer and more direct approach is as follows:
rewriting the equations,
8 = -X/6 + X/4
6 x 8 = -6X/6 + 6X/4
48 = -X + 6X/4
(48)x4 = -4xX + 4x6X/4
192 = -4xX + 6X
192 = 2X
X = 192/2 = 96

lcd of 6 and 4 = 12
2x - 3x = -96
x = 96

2x - 3x = - 96
- x = - 96
x = 96
