Write a system of equations associated with the augmented matrix. Do not try to solve.
A. 6x + 8y + 5z = -2
| 3x | + 3z = 4 |
| 9x | + 9z = 2 |
B. 6x + 8y + 5z = -2
| 3x | + 3z = | 4 |
| 9x + 9y | = | 2 |
C. 6x - 8y + 5z = -2
| 3x | + 3z = -4 |
| 9x + 9y | = -2 |
D. 9x + 3y + 6z = -2
| 9x | + 8z = 4 |
| 3y + 5z | = 2 |
