Answer:

5 years ago

Let Kelly's age be x

Jake's age is 4x

5 years later

Kelly's age is x + 5

Jake's age is 4x+5

The sum of both their ages is 60. The equation will be

x + 5 + 4x + 5 = 60

5x + 10 = 60

5x = 60 - 10

x = 50/5 = 10

So Kelly is (10 + 5) 15 years old.

Jake is (4*10 + 5) = 45 years old
