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
