4x+y=-17
-3x+y=4
Please help me solve each system of equation and show your work.

  • Math -

    Point: There is just one system of equations here.

    Just subtract them as they appear:

    7x = -21
    x = -3

    plug that back into either equation:

    4(-3) + y = -17
    -12 + y = -17
    y = -5
