Answer: (I'm not really sure what this means. Actual answer is in bold) more than one answer, 4 and -11 would work
The sum of the digits in each expression is 15.
7 + 3 + 5 = 15
8 + 4 + 3 = 15
9 + 5 + 1 = 15
If this is the right way to solve the problem, then 6 + 5 + 4 = 15 which gives us the answer is 4.
