@hartnn Shouldnt the division operation be done first? Since there is no parentheses?

No, there wasn't but for some reason, a sneak at the answers did say it was 3a/2. I guess it might have been a typo :/

if the answer is 3a/2
then there certainly is parenthesis.

without the parenthesis, the problem is too complicated to simplify , as indicated by wolf.
