To solve this problem you must apply the proccedure shown below:

1. Apply the Distributive property:

[tex]\frac{9}{2}(8-x)+36=102-\frac{5}{2}(3x+24)\\\frac{72}{2}-\frac{9}{2}x+36=102-\frac{15}{2}x-\frac{120}{2}[/tex]

2. Now, you must simplify:

[tex]36-\frac{9}{2}x+36=102-\frac{15}{2}x-60[/tex]

3. Add the like terms:

[tex]-\frac{9}{2}x+\frac{15}{2}x=102-60-36-36\\\frac{6}{2}x=-30[/tex]

4. Simplify:

[tex]3x=-30[/tex]

5. Solve for x. Divide -30 by 3:

[tex]x=\frac{-30}{3}\\x=-10[/tex]

The answer is: [tex]x=-10[/tex]
