The calculator function that puts the augmented matrix
![\left[\begin{array}{cc|c}2&4&8\\6&3&-3\end{array}\right]](https://tex.z-dn.net/?f=%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D2%264%268%5C%5C6%263%26-3%5Cend%7Barray%7D%5Cright%5D%20%20)
into reduced row-echelon form will give you an identity matrix in the left columns and the solution in the rightmost column:
![\left[\begin{array}{ccc}1&0&-2\\0&1&3\end{array}\right]](https://tex.z-dn.net/?f=%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%260%26-2%5C%5C0%261%263%5Cend%7Barray%7D%5Cright%5D%20%20)
This corresponds to the first selection.
