16-4(5-x)=8

Step #1- 16-4 = 12

Step #2- 12(5-x)  (multiply everything in the parenthesis by 12)   
               12 * 5 = 60      12 * -x = -12x

Step #3- 60 + -12x =8
              +60 -60 + -12x = 8 - 60
               -12x = 52
                -12/-12 = 52/-12
                      x = -52/12


Your answer is: x = -52/12 

Have an amazing day!
