1. Go to the matrix editor: [Shift] [4]
2. Select a matrix to edit and press (for example, choose M1): [Enter]
3. Enter the values into the matrix (let's assume we're entering our coefficient matrix); exit by pressing: [Esc]
4. Edit a new matrix: [Shift] [4] and select another matrix (for example M2)
5. Enter the constants column into this matrix. For example, if your system is
\[ \begin{array}{ll}
2x+3y & = 5\\
5x+2y & = 1
\end{array} \]
then the you would enter the 5 and 1 (as a column) into M2
6. In the Home screen, just type: M2 / M1

Or, you can enter in the entire system into a single matrix (again, let's pretend we're using M1) and just type RREF(M1) at the home screen.
