Answer:
x = 22
Step-by-step explanation:
I interpreted your problem as:
[tex]\frac{1}{2} (x+18) = 4(2x-6)-9x[/tex]
I simplified the problem to:
[tex]\frac{1}{2} x+9 = 8x-24-9x[/tex]
I combined like terms:
[tex]\frac{1}{2} x+9 = -x-24[/tex]
I moved all x to one side and all other constants to the other:
[tex]\frac{3}{2} x = -33[/tex]
I divided by 3/2 (1.5) on both sides to isolate x:
[tex]x = 22[/tex]
Hope it helps! (:
