Questions:
Gauss-Jordan elimination to solve system of linear equations
Use the Gauss-Jordan Method to solve each of the following systems of equations.
1.x + y = -1
y + z = 4
x + z = 1
2. 2x - y + z = 1
3x + y + z = 0
7x - y + 3z = 2
Please provide me the detailed steps on how to arrive at the answer to these problems.
