@ Karthik
Father's present age - Son's age = Father's age at the time of Son's birth.
Father's present age - Son's age = Father's age at the time of Son's birth.

Father Son.
Present age -> 38 let be 'x'.
At Birth -> 38-x (x-x) = 0.
By statement: I was means father was was as old as you as you are at the present i.e. son at the time of son's birth so,
Present age of son = x years.
Fathers age at son's birth = (38-x).
Just equate it: x = 38-x.
x = 19.
They want 5 years ago so 19-5 = 14.
Present age -> 38 let be 'x'.
At Birth -> 38-x (x-x) = 0.

Hai.
Already we initialed that son age is:x.
Then how? We again take x as father age at the time of sons birth.
