Answer:
Son's age = 10 years
Father's age = 30 years
Step-by-step explanation:
Son's age = x
Father's age = 3x
Five years ago:
Son's age = x - 5
Father's age = 3x - 5
5(x - 5) = 3x - 5
5x - 25 = 3x - 5
5x - 3x = -5 + 25
2x = 20
x = 20/2
x = 10
Son's age = x = 10 years
Father's age = 3x = 3 × 10 = 30 years
Check ⇒
Five years ago:
Son's age = x - 5 = 10 - 5 = 5
Father's age = 3x - 5 = 30 -5 = 25
5 × 5 = 25
25 = 25
