    *URGENT* test help

    please help i need to know these by tonite and no one ive talked with understands them, thanks.

    complete the ordered triple:

    7x - y + z = -24
    3x + 2y - 3z = 0
    x - 3y + 2z = -9

    x + y + z = -3
    2x + 5y + 2z = -18
    -x + 9y - 3z = -43

    6x + 3y + z = -33
    x - 3y + 2z = -11
    17x - 2y + 3z = -94

    4a + 3b + c = -9
    a - 3b + 2c = 5
    11a - 2b + 3c = -14

    6x + 3y + z = -4
    x - 3y + 2z = 15
    17x - 2y + 3z = 41

    3x + 3y + z = -8
    x - 3y + 2z = -13
    8x - 2y + 3z = -51

    5x - y + z = -33
    2x + 2y - 3z = 8
    x - 3y + 2z = -27

    x + y + z = 10
    2x + 4y + 2z = 28
    -x + 9y - 3z = 18

    5r - s + t = -8
    2r + 2s - 3t = -38
    r - 3s +2t = 26

    4a + 7b = -29
    8a + 3c = -13
    6b + 3c = -15

    x + y + z = 73
    -2x + 2y = 8
    x - z = -9

    a+b+c = 37
    -2a + 3b = 20
    a - c = -9

    I'm not sure what your question is. Do you need to find each coefficient for each of the sets of equations?
