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.

  • Math -

    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
