Answer:

Let the age of the mother be x and twins be y.
Set up two equations as per information given:
- 1) x - y = 33, (age relation now)
- 2) x + 3 = 2(y + 3 + y + 3) (relation in 3 years time)
Simplify the second equation and substitute x = y + 33:
- x + 3 = 2(2y + 6)
- x + 3 = 4y + 12
- y + 33 + 3 = 4y + 12
- y + 36 = 4y + 12
- 4y - y = 36 - 12
- 3y = 24
- y = 8
The twins are 8 now.
