Use Matrix Inversion to Solve the Given System of Linear $\begin{aligned}4 x - 7 y - z & = 3 \\- z & = 1 \\x - 2 y + 3 z & = - 5\end{aligned}$

Short Answer

Use matrix inversion to solve the given system of linear equations.
​ $\begin{aligned}4 x - 7 y - z & = 3 \\- z & = 1 \\x - 2 y + 3 z & = - 5\end{aligned}$ ​ $x=\frac{\text { }}{\text { }}$ ​ $y=\frac{\text { }}{\text { }}$ ​ $z=\frac{\text { }}{\text { }}$
