    Y = - 2x + 3

    2x + 4y = - 8

    y = - 2x + 3

    y + 2x = 3

    2x + 4y = - 8

    Subtract those equations

    3y = - 11

    y = - 11/3

    y = - 2x + 3

    -11/3 = - 2x + 3

    2x = 3 + 11/3

    x = 3/2 + 11/6

    x = 20/6

    x = 10/3

    therefore above lines will intersect in this (10/3, - 11/3) coordinates
