Answer 1

Supposition

• let the present age of Son be X.
• and the present age of father be 3x.

Linear equation:-

:$\implies$ 2(x+20) = 3x+20

Solution:-

:$\implies$ 2(x+20) = 3x+20

:$\implies$ 2x+40 = 3x+20

:$\implies$ 20 = x

hence, the present age of Son is 20 years

and the present age of the father is 20×3 = 60 years
