    x = - 3

    y = 2

    Step-by-step explanation:

    Set new equation:

    y=8+2x

    Now input - 3x-y=7 for y

    -3x - (8x+2x) = 7

    Simplify

    -5x-8=7

    Solve by substituion

    y=8+2x

    -5x-8=7

    y=8+2x

    x=-3

    Now plug in for x in y=8+2x

    y=8+2 (-3)

    y=2

    Answer:

    x=-3

    y=2
