Question

Write the matrix equation as a system of linear equations without matrices.

Answer 1

`\begin{gathered} 8x+4y-3z=-8 \\ -8x-6y-z=-1 \\ 5x-y+8z=5 \end{gathered}`

EXPLANATION :

From the problem, we have the matrix :

`\begin{bmatrix}{8} & {4} & {-3} \\ {-8} & {-6} & {-1} \\ {5} & {-1} & {8}\end{bmatrix}\begin{bmatrix}x \\ y \\ z\end{bmatrix}=\begin{bmatrix}-8 \\ -1 \\ 5\end{bmatrix}`

The first column is with x, the second column is with y and the third column is with z.

The equations will be :

`\begin{gathered} 8x+4y-3z=-8 \\ -8x-6y-z=-1 \\ 5x-y+8z=5 \end{gathered}`
