Question

5 years ago fothers age was 7 times his son age and 5 years later his age will be 3 times his son age find present ages​

Answer 1

Answer:

Step-by-step explanation:

present age of father= x

present age of son=y

so, x-5 = 7(y-5)

= x-5 = 7y - 35

x-7y = -30 ------1

then, x+5 = 3(y+5)

x+5 = 3y + 15

x-3y = 10--------2

so by elimination method,

y=10

so x - 3(10) = 10

so x=40

so father age is 40 and his sons age is 10
