Answer:
thats correct
Step-by-step explanation:
Sorry what what is the question?
You do the sum(40) subtracted by 8, the answer from that divided by 2 since Erin's two times younger.
40-8=32
32÷2=16
Then if you want to check it you do the opposite and get the same sum(40) so 16×2=32 and 32+8=40
I am sorry there is not enough information to work with plus the question doesn't even make sense.
