Answer:
30
Step-by-step explanation:
Let m represent the mother's age in 3 years. At that point in time, her age is twice a twin's age, which is m-33:
m = 2(m -33)
m = 2m -66 . . . . eliminate parentheses
66 = m . . . . . . . . add 66-m
In 3 years, the mother's age will be 66. Each twin is now 36 years younger.
The twins are 30 years old now.
