Answer:

Now: Carolyn 18 yo, Alfred 12 yo

Explanation:

Use X represent Alfred's age now, then Carolyn's age is (X+6)

6 years ago, their ages should be current age minus 6. So Alfred's age was (X-6), Carolyn's age was ((X+6)-6).

As 6 years ago, Carolyn's age was twice as Alfred's. So

((X+6)-6)=(X-6)×3

X=12 which is Alfred' current age

X+6=18 which is Carolyn' current age
