First distribute the 6 into the 7x+18, and the 4 into the x+8, and then solve for x.
6(7x+18)=(x+8)4
(6*7x) + (6*18) = (x*4) + (4*8)
42x + 108 = 4x + 32
42x + 108 = 4x + 32
- 108 -108
-------------------------------
42x = 4x - 76
-4x -4x
-------------------------
38x = -76 ---Divide both sides by 38
38/38x = -76/38
x = -76/38
x = -2
