Let the present age of Aftab be 'x'
Let the present age of Daughter be 'y'
A.T.Q
7 years ago, Age of Aftab = x-7
Age of daughter =y-7
Aftab =7 times of Daughter.
(x-7)=7(y-7)
x-7=7y-49
x-7y=-49+7
We got,
X-7y=-42.--------(1)
After 3 years,
Age of Aftab =x+3
Age of daughter =y+3
Aftab =3 times of Daughter
x+3=3(y+3)
x+3=3y+9
x-3y= 9-3
We got,
x-3y=6----------(2)
Now.... Find the solution for both the equations, i.e., (1) and (2).
[Solutions and the graph drawn in the attachment. Please do check it ].
Thanks ✌❤
