1) Solve the system of linear equations using the Gauss-Jordan elimination method.
| 2x | + | 4y | − | 6z | = | 56 |
| x | + | 2y | + | 3z | = | −2 |
| 3x | − | 4y | + | 4z | = | −21 |
(x, y, z) =
2) Solve the system of linear equations using the Gauss-Jordan elimination method.
| 5x | + | 3y | = | 9 |
| −2x | + | y | = | −8 |
(x, y) =
