    Answer:

    -2

    Step-by-step explanation:

    2x-y=-8-1equation

    2x=-8+y

    x=-8+y -2equation

    2

    then, taking 1st equation;

    2x-y=-8

    2(-8+y/2)-y=-8

    -16+2y-y=-8

    4

    -16+2y–4y=-8

    4

    -16-2y=-8*4

    -2y=-32+16

    y=-16/-2

    y=4

    for x

    x=-8+y

    2

    x=-8+4

    2

    x=–4

    2

    x=-2
