A system of linear equations is said to be consistent iff the rank of the associated augmented matrix is equal to the rank of the associated coefficient matrix (this means that the system of equations has at least one solution). The system of linear equations is inconsistent otherwise. Solution Forms:

Solving Systems of Linear Equations in Three Variables
Create a coefficient matrix(3X3) and a constant matrix(3X1) as shown. Once again, the matrix shown is for the system of equations: Copy the coefficient matrix and raise it to –1 power to indicate the inverse matrix. Multiply this by a copy of the constant matrix. When you press ·, you will see the solution to the system.

3x3 Linear Systems of Equations - Texas Instruments
A 33 system of linear equations can also be solved by using the inverse matrix method. Because this process is very long and cumbersome to do algebraically, it is normally done using a graphing calculator. Solving a 33 system using technology will be presented in the Appendix.
