Assuming your equation is equal to zero (which must be included if you want to solve for X), we set the whole thing = 0, simplify, and isolate the variable. 

- 1/4( 24 - 16x) + 9 = 0

Distribute the - 1/4 to each term in the parentheses

- 1/4(24) - 1/4(- 16x) + 9 = 0
- 6 + 4x + 9 = 0

Combine like terms

4x + 3 = 0

Subtract by 3 on both sides.

4x = - 3

Divide both sides to isolate the variable

x = - 3/4
