Solve the system by inverting the coefficient matrix and using the following theorem:

Solve the system by inverting the coefficient matrix and using the following theorem:
If A is an invertible n X n matrix, then for each n x 1 matrix b, the system of equations Ax = b has exactly
one solution, namely, x = A-b.
x + y + z = 11
x + y – 10z = 22
- 10x + y + z = 0
