Answer 1

Answer:

father's age = 30 years

son's age = 6 years

Step-by-step explanation:

giving the explanation in English

let the present age of father be x

let the present age of son be y

six years after father's will be 3 times that of son's age

x + 6 = 3(y + 6)

x + 6 = 3y + 18

x - 3y = 18 - 6

x - 3y = 12 equ (1)

three years ago father's age was 9 times of son's age

x - 3 = 9(y - 3)

x - 3 = 9y - 27

x - 9y = -27 + 3

x - 9y = - 24 equ (2)

subtract equ (2) - (1)

(x - 9y) - (x - 3y) = - 24 - 12

x - 9y - x + 3y = - 36

- 6y = -36

6y = 36

y = 36/6

y = 6

substitute y = 6 in equ (1)

x - 3y = 12

x - 3(6) = 12

x - 18 = 12

x = 12 + 18

x = 30

therefore father's age = x = 30 years

son's age = y = 6 years

hope you get your answer
