Answer:

Robert is 17 years old

Kent is 13 years old

Explanation:

Alright, let's say that Robert is X years old, and Kent is X - 5 Years old, since he is 5 years younger. Since their ages together add up 39 years old, set these values next to one another.

x + x + 5 = 39

Add Like Terms

2x + 5 = 39

Cancel out the 5

2x = 34

Divide by 2

x = 17

With this, x is 17. This means that Robert is 17 years old since his age was x. With Kent he is 13 years old since 17 - 5 = 13.
