If I were to do this problem, I'll start with "naming" the variables of "FIND". In this problem the "FIND" is:

Amount money Sue put in at the beginning = S

I know sue has 7$ more \(\displaystyle \ \ \to \ \\) Amount money Angela put in at the beginning = S - 7

Now continue with creating equations (and solving those) from other given conditions.

However, I think the wording of this problem is flawed.
