Step-by-step explanation:
5 years ago,
Let the age of the son be x years
father's age = 7x years
After 5 years, that is the present year
son's age = x+5 years
father's age = 7x+5 years
7x+5 = 3(x+5)
7x+5 = 3x+15
7x-3x = 15+5
4x = 20
x = 20/4
= 5
Son's age = 10 years
Father's age = 40 years
Hope this helps
