5. $\left[\begin{array}{lll}? & ? & ? \\ ? & ? & ? \\ ? & ? & ?\end{array}\right]\left[\begin{array}{l}x_{1} \\ x_{2} \\ x_{3}\end{array}\right]=\left[\begin{array}{c}3 x_{1}-2 x_{3} \\ 4 x_{1} \\ x_{1}-x_{2}+x_{3}\end{array}\right]$
$\left[\begin{array}{ccc}3 & 0 & -2 \\ 4 & 0 & 0 \\ 1 & -1 & 1\end{array}\right]\left[\begin{array}{l}x_{1} \\ x_{2} \\ x_{3}\end{array}\right]=\left[\begin{array}{c}3 x_{1}-2 x_{3} \\ 4 x_{1} \\ x_{1}-x_{2}+x_{3}\end{array}\right]$
By inspection
