![\left[\begin{array}{cc}5&2\end{array}\right] \left[\begin{array}{c}x\\y\end{array}\right]= -7](/tpl/images/0022/1065/da489.png)
⇒ 5(x) + 2(y) = -7⇒ 5x + 2y = -7![\left[\begin{array}{cc}3&-4\end{array}\right] \left[\begin{array}{c}x\\y\end{array}\right]= -6](/tpl/images/0022/1065/1a9ab.png)
⇒ 3(x) + -4(y) = -6⇒ 3x - 4y = -6
