Simplificando a equação, teremos: x= \frac{6.(B-A)-C-A}{-5}

6(B-A)=\left[\begin{array}{ccc}-12&-6&12\\30&18&6\end{array}\right]
C-A=\left[\begin{array}{ccc}1&1&1\\-1&0&-1\end{array}\right]
6(B-A)-C-A=\left[\begin{array}{ccc}-17&-9&12\\29&16&5\end{array}\right]
X=\left[\begin{array}{ccc}\frac{17}{5}&\frac{9}{5}&-\frac{12}{4}\\&&& \frac{29}{5}& \frac{16}{5}&-1\end{array}\right]
