A=Albert's age; F=Father's age=A+24
.
F+8=2(A+8)
(A+24)+8=2A+16
A+32=2A+16
16=A
ANSWER 1: Albert is 16 years old.
.
F=A+24=16+24=40
ANSWER2: Father is 40 years old.
.
CHECK:
F+8=2(A+8)
40+8=2(16+8)
48=2(24)
48=48

Answer by fractalier(6550) (Show Source): You can put this solution on YOUR website! Call Albert's and his father's age NOW, a and f.
Then we have
f = a + 24
In 8 years,
f + 8 = 2(a + 8)
Now substitute and get
a+24 + 8 = 2(a + 8)
a + 32 = 2a + 16
Now subtract a from both sides and then subtract 16 and get
32 = a + 16
a = 16
Then we have
f = 40 Answer by MathTherapy(10552) (Show Source): You can put this solution on YOUR website!
Albert's father is 24 years old 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?
Let father's current age, be F
Then Albert's is: F - 24
We then get: F + 8 = 2(F - 24 + 8)
F + 8 = 2(F - 16)
F + 8 = 2F - 32
F - 2F = - 32 - 8
- F = - 40
F, or father's current age = , or
