Step-by-step explanation:
I am explaining read carefully
let the age of son is =x
Man age= x+5
after two years son=x+2
Man age= x+5+2
=x+7
according to the question
3(x+2)=(x+7)
3x+2=x+7
3x-x = 7-2
2x=5
x= 5/2
x= 2.5
son age = 2 years 5 months
man age = x+5
= 2.5+5
=7.5= 7 years 5months
after two years son=x+2
=2.5+2
=4.5=4years 5 months
Man age= x+5+2
=2.5+5+2
= 9.5= 9years 5 months
