Question 22082
First you must distribute the number (or variable) in front of the ( ) to the inside of the ( ).  This is done by multiplying 5 times everything in the ( ).  Then just solve for x.  I will work the problem. If you have questions please let me know.

5(2x-3) + 8 = 9
10x-15  + 8 = 9
10x = 15 -8 + 9
10x = 16
x = 16/10  = 8/5      this answer will depend on what form your instuctor wants
