Thread: *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

To learn, study some online lessons regarding systems of linear equations.

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