Problema Solution

A man is 4 times as old as his son. How old is each now if the sum of their age is 65?

Answer provided by our tutors

let


x = the age of the man

y = the age of his son


a man is 4 times as old as his son


x = 4y


the sum of their age is 65


x + y = 65


by solving the system of equations


x = 4y

x + y = 65


we find


x = 52 years


y = 13 years


the man is 52 years old.

his son is 13 years old.
