The Answer of Solve the System of Equations by Using an Inverse Matrix$$\begin{aligned}
8 x - 9 y - z & = - 12 \
x + 2 y + 7 z & = 64 \
- 7 x + y + z & = - 23
\end{aligned}$$

Solve the System of Equations by Using an Inverse Matrix $\begin{aligned}8 x - 9 y - z & = - 12 \\x + 2 y + 7 z & = 64 \\- 7 x + y + z & = - 23\end{aligned}$

Definitions:

Solve the System of Equations by Using an Inverse Matrix 8x−9y−z=−12x+2y+7z=64−7x+y+z=−23\begin{aligned}8 x - 9 y - z & = - 12 \\x + 2 y + 7 z & = 64 \\- 7 x + y + z & = - 23\end{aligned}8x−9y−zx+2y+7z−7x+y+z​=−12=64=−23​
