    Y=-2/3x + 2

    y=3x-2

    one because the slopes are different

    A) 2x+3y=6

    B) 3x-y=2

    Multiplying equation B by 3

    9x - 3y = 6 then adding it to equation A

    2x + 3y = 6

    11x = 12

    x = 12 / 11

    2x + 3y = 6

    3y = 6 - 2x

    y = 2 - (2/3) x

    y = 2 - (2/3) * (12/11)

    y = 2 - 8/11

    y = 14 / 11

    Therefore, it has one solution
