34Solve the linear system: x + 4y = 4x- y = -6First make sure that the two equations are lined up by their variables. (Which they are)1. Press [2 nd ] then press [MATRIX]2. Move over from NAMES to EDIT using the arrow keys3. Now press [ENTER]4. Make sure that size of the matrix is the size that you want. (In this case it is 2 x 3,because there are two columns and 3 rows). If the system is larger or smallerchange the numbers next to where it says MATRIX[A].5. Now move your curser into the matrix using the arrow keys and input thenumbers of your system into the matrix.
356. Press [2 nd ], then press [Quit] once you have the matrix you want on the screen,this will take you back to the home screen.7. Now Press [2 nd ], then press [CATALOG]8. Now Press [r] and look for rref( and press [ENTER], rref( should appear on yourhome screen9. Press [2 nd ], then press [MATRIX]10. Make sure that that the number of the matrix that you imputed into your calculatoris highlighted, in this case 1: [A] 2x 3, and press [ENTER]
