Let the present age of the son be x years and two years ago his age would be ( x - 2 ) years .
So present age of father be 7x years and 2 years ago father's age would be ( 7x - 2 ) years
Present age of father = 7x years
Present age of son = x years
According to the question :
age of father 2 yeard ago = 13 × age of son years ago
( 7x - 2 ) years = 13( x - 2 ) years
7x - 2 = 13x - 26
26 - 2 = 13x - 7x
24 = 6x
4 = x
Therefore,
present age of son = x years = 4 years
present age of father = 7x year = 7( 4 ) years = 28 years
So present age of father be 7x years and 2 years ago father's age would be ( 7x - 2 ) years
Present age of father = 7x years
Present age of son = x years
According to the question :
age of father 2 yeard ago = 13 × age of son years ago
( 7x - 2 ) years = 13( x - 2 ) years
7x - 2 = 13x - 26
26 - 2 = 13x - 7x
24 = 6x
4 = x
Therefore,
present age of son = x years = 4 years
present age of father = 7x year = 7( 4 ) years = 28 years

Let present age of son be x yrs.
present age of father be 7xyrs.
According to the question:-
• two years ago
age of father (7x-2)yrs
age of son = (x-2) yrs
7x-2 = 13 ( x-2)
7x-2 = 13x-26
7x-13x = -26+2
-6x = -24
x = -24 / -6
