8. albert's father is 24 years older than albert is. in 8 years, his father will be twice as old as albert. how old is albert now? how old is his father?

Albert´s ftather age=x
Albert age=y

We suggest this system of equations:
y=x-24
x+8=2(y+8)

we solve this system of equation by substitution method.

x+8=2[(x-24)+8]
x+8=2(x-16)
x+8=2x-32
x-2x=-32-8
-x=-40
x=40

y=x-24
y=40-24
y=16

Albert´s father is 40 years old, and Albert is 16 years old.
