Answer 5

You CAN multiply matrices, right? :D
Let
\[\Large A =\left[\begin{matrix}a_{11}&a_{12}&a_{13}\\a_{21}&a_{22}&a_{23}\\a_{31}&a_{32}&a_{33}\end{matrix}\right] \]
\[\Large \vec x = \left[\begin{matrix}x\\y\\z\end{matrix}\right]\]\[\Large B =\left[\begin{matrix}b_1\\b_2\\b3\end{matrix}\right]\]

Answer 6

Then that means your system is simply...\[\Large\left[\begin{matrix}a_{11}&a_{12}&a_{13}\\a_{21}&a_{22}&a_{23}\\a_{31}&a_{32}&a_{33}\end{matrix}\right]\left[\begin{matrix}x\\y\\z\end{matrix}\right]=\left[\begin{matrix}b_1\\b_2\\b_3\end{matrix}\right]\]
\[\Large A\vec x = B\]
