Answer:
Step-by-step explanation:
let present age of
Dylan=x
Renee=y
x+y=57
9 years ago
x-9=2(y-9)=2y-18
x=2y-18+9=2y-9
so 2y-9+y=57
3y=57+9=66
y=66/3=22
x+22=57
x=57-22=35
Dylan's present age=35 years
equation for first figure=2x+y=2
equation for second figure= 4x-y=8
(use formula x/a+y/b=1)
where, a=x component and b= y component..
