Question
Use matrices to solve the system.$$\left\{\begin{aligned} 2 x-y+4 z &=8 \\ -3 x+y-2 z &=5 \end{aligned}\right.$$
Step 1
The matrix form of the system is: $$\begin{bmatrix} 2 & -1 & 4 \\ -3 & 1 & -2 \end{bmatrix} \begin{bmatrix} x \\ y \\ z \end{bmatrix} = \begin{bmatrix} 8 \\ 5 \end{bmatrix}$$ Show more…
