aashiqafthabThe sum of the ages of a son and his father is 35 x + y = 35 the product of their ages is 150. xy = 150 x = 150/y Substitute x = 150/y into x + y = 35 150/y + y = 35
Common denominator = y 150 + y^2 = 35y y^2 - 35y + 150 = 0 (y - 5)(y - 30) therefor,Son's age is 5 years andThe father's age is 30 years

x + y = 35
the product of their ages is 150.
xy = 150
x = 150/y
Substitute
x = 150/y into
x + y = 35
150/y + y = 35
Common denominator = y
150 + y^2 = 35y
y^2 - 35y + 150 = 0
(y - 5)(y - 30)
therefor,Son's age is 5 years andThe father's age is 30 years
