This year, the sum of Mr. Bellini's age and his son's age is 38 years. 4 years ago, Mr. Bellini was 5 times as old as his son. How old is his son this year? How old is Mr. Bellini this year?

5 answers

Let x = son's age
Let 38-x = Mr. Bellini's age (since the sum of their ages must be equal to 38)
Set up the equation using the the second statement:
(38 - x) - 4 = 5(x - 4)
Solving,
34 - x = 5x - 20
34 + 20 = 6x
54 = 6x
x = 9 years old (son's age)
38-x = 29 years old (Bellini's age)

Hope this helps~ :3
