In your coding environment of choice, create variables for both the coefficient matrix, and the aug$-$

mented matrix, associated to the previous problem. Then apply a built$-$in row$-$reduced echelon form

$($RREF$)$ tool $($see Canvas for examples in Matlab and Python$).$ Show the outputs in your

submission, and confirm that the RREF of both match $($except for the final column$).$
