Use matrix inversion to solve the collection of systems of linear equations.
(a)
| x | 4y | + | 2z | = | 6 | |
| x | + | 2y | z | = | 1 | |
| x | + | y | z | = | 6 |
(x, y, z) =
(b)
| x | 4y | + | 2z | = | 4 | |
| x | + | 2y | z | = | 5 | |
| x | + | y | z | = | 2 |
(x, y, z) =
(c)
| x | 4y | + | 2z | = | 0 | |
| x | + | 2y | z | = | 0 | |
| x | + | y | z | = | 0 |
(x, y, z) =
