Use Matrix Inversion to Solve the System of Linear Equations $\begin{aligned}x + 2 y + z & = 17 \\x + y + z & = 10 \\3 x + y + z & = 4\end{aligned}$

Short Answer

Use matrix inversion to solve the system of linear equations.
​ $\begin{aligned}x + 2 y + z & = 17 \\x + y + z & = 10 \\3 x + y + z & = 4\end{aligned}$ ​ $x=\frac{\text { }}{\text { }}$ ​ $y=\frac{\text { }}{\text { }}$ ​ $z=\frac{\text { }}{\text { }}$
