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
