Code:

+-     -+   +- -+   +- -+
| A B C |   | x |   | D |
| E F G | * | y | = | H |
| I J K |   | z |   | L |
+-     -+   +- -+   +- -+

Just wanted to let you know that this forum supports LaTeX:
\[
\begin{bmatrix}
A & B & C \\
E & F & G \\
I & J & K
\end{bmatrix}
\cdot
\begin{bmatrix}
x \\
y \\
z
\end{bmatrix}
=
\begin{bmatrix}
D \\
H \\
L
\end{bmatrix}
\]
As I'm not fluent I often use this online LaTeX equation editor.

Kind regards
