$[\begin{array}{c} 10 & 4 & 10 & 1 & 0 & 0 & 4000 \\ 10 & 6 & 2 & 0 & 1 & 0 & 1800 \\ - 20 & - 8 & - 14 & 0 & 0 & 1 & 0 \end{array}]$

Step 1

Transpose the matrix by switching its rows to columns.

$[\begin{array}{c} 10 & 10 & - 20 \\ 4 & 6 & - 8 \\ 10 & 2 & - 14 \\ 1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \\ 4000 & 1800 & 0 \end{array}]$
