Can someone tell me how to solve my problem? Do I just start plugging in numbers or is there some rational to figure this out?

Sum of three numbers is -5. First, minus second, plus 4 times the third is -20. The third plus 4 times the first plus the second is -20.

a + b + c = -5

a - b + 4c = -20

4a + b + c = -20

looks like a very simple 3 equation in 3 variables question.

Hint: add the first two, then the last two, and go from there

I got a=-5

b=3

c=-3
