Write the Matrix Equation as a System of Linear Equations

Multiple Choice

Write the matrix equation as a system of linear equations without matrices.
- $$\left[ \begin{array} { l l l } 3 & 2 & 8 \\9 & 0 & 7 \\4 & 9 & 0\end{array} \right] \left[ \begin{array} { l } x \\y \\z\end{array} \right] = \left[ \begin{array} { r } - 2 \\4 \\2\end{array} \right]$$

A) $3 x + 2 y + 8 z = - 2$
$9 x + 7 z = 4$
$4 x + 9 y = 2$
B) $3 x - 2 y + 8 z = - 2$
$9 x + 7 z = - 4$
$4 x + 9 y = - 2$
C) $3 x + 2 y + 8 z = - 2$
$9 x + 7 z = 4$
$4 x + 9 z = 2$
D) $3 x + 2 y + 8 z = - 2$
$9 x + 7 y = 4$
$4 x + 9 z = 2$
