Write the system of linear equations represented by the augmented matrix. Use x, y, z, and, if necessary, w for the variables.
A.
| 9x + 8y + 8z | = | -2 |
| 2x + y + 9z | = | 4 |
| 9x + 5y + z | = | 2 |
B.
| 9x + 8y + 8z | = | -2 |
| 2x + 9z | = | 4 |
| 9x + 5z | = | 2 |
C.
| 9x - 8y + 8z | = | -2 |
| 2x + 9z | = | -4 |
| 9x + 5y | = | -2 |
D.
| 9x + 8y + 8z | = | -2 |
| 2x + 9z | = | 4 |
| 9x + 5y | = | 2 |
