Solution Steps
Step 1: Form the Augmented Matrix
The augmented matrix is formed by combining the coefficient matrix A with the constants vector b.
Step 2: Apply Gauss-Jordan Elimination
Using Gauss-Jordan elimination, we reduce the augmented matrix to reduced row echelon form (RREF).
Step 3: Solve for Variables
From the RREF, we directly read off the solutions for the variables.
