Question

if the present age of son and father are expressed by x and y respectively and after 10 years father will be twice as old as his son. Write relation between x and y ​

Answer 1

Well if they are x and y now then after 10 yrs too they will be father and son.   Also as an equation =

10 + 2x = y + 2

Answer 2

Step-by-step explanation:

father's age = y

son's age = x

after 10 years,

father's age = 2( x+10)

y+10 = 2( x+10)

y = 2x + 10
