    Multiply - x+4y=28 by 2

    -2x+8y=56

    add to first equation

    2x+10y=-20

    -2x+8y=56 +

    0x+18y=36

    18y=36

    divid 18

    y=2

    subsitute

    -x+4y=28

    -x+4 (2) = 28

    -x+8=28

    subtract 8

    -x=20

    multipy - 1

    x=-20

    x=-20

    y=2

    (x, y)
