Answer:
Carl=15
Eve= 18
Jenna=9
Step-by-step explanation:
We know that Carl is 6 years older than her and that Eve is twice her age.
So, I started playing around with combinations and found my answer
J+15+18=42
Add these together
J+33=42
Subtract
J=9
Try and see if the equation makes since
9+15+18= 42 !!! Correct
