![\vec A = \left[\begin{array}{ccc}7&6\\2&-8\end{array}\right]](/tpl/images/0771/6236/55c30.png)
.![\left(\vec A|\vec B\right) = \left[\begin{array}{ccc}7&6&6\\2&-8&4\end{array}\right]](/tpl/images/0771/6236/b5c9c.png)
.
linear equations with 
- Coefficient matrix, a 
matrix.
- Variable matrix, a 
matrix.
- Equivalence matrix, a ![\left[\begin{array}{ccc}7&6\\2&-8\end{array}\right]\left[\begin{array}{ccc}x_{1}\\x_{2}\end{array}\right] = \left[\begin{array}{ccc}6\\4\end{array}\right]](/tpl/images/0771/6236/983c6.png)
