Answer:

x=6

y=0

Step-by-step explanation:

Let the age of Aftab's daughter be x

and Aftab's age be y

seven years ago,

Their age was, x-7 and y-7.

And three years later their age would be x+3 and y+3.

Now, ATQ,

7(x-7)=y-7........eq(1)

x+3=(y+3).........eq(2)

taking the value of y from eq(1) we get,

7x-49=y-7

y=7x-42

putting the value of y in eq(2)

x+3=3y+9

x+3=21x-126+9l

21x-126+9-x-3=0

20x-129+9=0

20x-120=0

dividing by 20,

x-6=0

x=6

putting the value of x=6, in eq(1)

7*6-42=y

y=0
