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
