Explicação passo-a-passo:

a.

$\large\mathsf{\begin{vmatrix}27&-3&15\end{vmatrix}} - \large\mathsf{\begin{vmatrix}12&50&20\end{vmatrix}} = \large\mathsf{\begin{vmatrix}15&-53&-5\end{vmatrix}}$

b.

$\large\mathsf{\begin{vmatrix}0&-6\\2&23\end{vmatrix}} + \large\mathsf{\begin{vmatrix}10&-4\\-1&-7\end{vmatrix}} = \large\mathsf{\begin{vmatrix}10&-10\\1&16\end{vmatrix}}$
