                 3x + 15 = 5x

                -3x          -3x

                        15 = 2x

                      ÷2   ÷2  

                       7.5 = x

7 1/2 hours =x

Step-by-step explanation:

Hi, to answer this question we have to express the information in ratios.

Mr. Branche's time per job : 1job /5hours

MR Branches’ son = 1 job /x hours

Both = 1job/3 hours

If we add, r branches and his son's work, we obtain the total spent time by both of them.

1/5 + 1/x = 1/3

Solving for x:

1/x = 1/3 -1/5

1/x = 2/15

1 ( 2/15) =x

7 1/2 hours =x
