Question

if present age of son and father are expressed by X and y respectively and after ten years father will be twice as old as his son write relation between X and y​

Answer 1

Answer:

relation is y=2x+10

Step-by-step explanation:

present age of son =x

present age of father=y

10 years later

son's age = x+10

father's age =y+10

the father is twice the son's age

y+10=2(x+10)

simplify

y+10=2(x+10)

y+10=2x+20

y= 2x+10
