C = $left[begin{array}{ccc}-4&2\-3&1\end{array}right]$
3C = 3 $left[begin{array}{ccc}-4&2\-3&1\end{array}right]$
3C = $left[begin{array}{ccc}-12&6\-9&3\end{array}right]$

Determinan 3C = $left[begin{array}{ccc}-12&6\-9&3\end{array}right]$
Determinan 3C = (-12 x 3) – (-9 x 6)
Determinan 3C = – 36 – (-54)
Determinan 3C = -36 + 54
Determinan 3C = 18
