Answer 2

Answer:

21. x = 40 , y = 10

Step-by-step explanation:

Let the age of son = y

the age of father = x

now five years ago

x-5 = 7(y-5)

x-5 = 7y-35

x-7y = -30

now five years hence

x+5 = 3(y+5)

x+5 = 3y+15

x-3y = 10

now solve both the equations by using elimination method

x-7y = -30

x-3y = 10

- + -

-4y = -40

y = 10

put y in any of the equation

x-3y = 10

x-30 = 10

x = 40

hope it helps..........
