Question

if the present ages of a son and father are expressed as x.and y respectively and after ten years father will be twice as old as son .write the relation between x and y

Answer 1

Let the son's age be x and father's age be y
After 10 years,
Son's age = 10+x
Father's age = 10+y
A/Q = 2(10+x) = 10+y
20+2x = 10+y
2x-y = -10
