x=-2/3

Explanation:

Original solution
Place on a common denominator and solve the resulting linear equation.
16/(8x + 48) = (9x + 54)/ (8x + 48) - 32/(8x + 48)

16 - 54 + 32 = 9x

-6 = 9x

-2/3 = x

Simplier solution
2/(x+6)=9/8-4/(x+6)
2/(x+6)+4/(x+6)=9/8
6/(x+6)=9/8
Multiply both sides by (x+6) and divide by 9/8
6*8/9=x+6
x=(2*8)/3-6=16/3-6=5 1/3-6=-2/3
The solution is -2/3.
