• An Augmented Matrix can also be written using Matrix-Vector Product like below:

$$ \left[\begin{array}{ccc|c}
2 & 0 & 1 & 3\
0 & 1 & 1 & 2 \end{array}\right] $$ $$ \begin{bmatrix} 2 & 0 & 1 \\0 & 1 & 1 \end{bmatrix} \begin{bmatrix} x_1 \\x_2 \\x_3 \end{bmatrix}= \begin{bmatrix} 3 \\2 \end{bmatrix} $$
