  1. -2x + 9y = 3
    -3x - 4y = 22

    first equation times 3
    -6x + 27y = 9
    second equation times -2
    6x + 8y = -44

    add the new equations:
    35y = -35
    y = -1
    sub back into original -2x + 9y = 3
    -2x - 9 = 3
    -2x = 12
    x = -6

    x= -6 , y = -1

    of course you should realize that there are many other ways to solve this, that was just my choice.
