Question

12-4/5(x+15)=4 Please show work.

Answer 1

12-4/5(x+15)=4   (do  distrib. property first
12-4/5x-12=4      (add -12 for both sides
12-4/5x=16         (subtract 12 for both sides
-4/5x=4               (flip -4/5 like this:5/-4 for both sides
5/-4*-4/5x=4*5/-4 ( the left hand side of the equation will be canceled out so it will be x by itself and multiply 5 and 4 togeher to get 20 and divide by -4

final answer: x=-5
