Solve the following system of equations by reducing its augmented matrix to reduced row echelon form (RREF). . If the solution is unique, clearly state the solution outside of a matrix.
If there is no solution, explain how you know from the procedure that there is no solution. •
If there are infinitely many solutions, express the solution to the system using one or more parameters. (Vector form is fine, but not required)
21 - 22 + 2x3 - 24 = -1
2x1 + x2 - 2003 - 2x4 = -2
- 21 +232 - 433 + 4 = 1
321 - 324= -3
