Question

A man is 20 years older than his son. If the sum of their ages is 64, find the age of the son.

Answer 1

22 years old

Explanation:

let the son's age be x then the father's age is x + 20 , so

x + x + 20 = 64

2x + 20 = 64 ( subtract 20 from both sides )

2x = 44 ( divide both sides by 2 )

x = 22

that is son is 22 years old
