Use Cramer's rule to solve the system of equations. If D = 0, use another method to determine the solution set.
$\begin{aligned}
x - y & + 5 z = 4 \
3 x & + z = 0 \
x + 4 y & + z = - 16
\end{aligned}$
A) {(0,-4,4)}
B) {(0,0,-4)}
C) {(0,-4,0)}
D) Cramer's rule does not apply since $\mathrm { D } = 0 ; \varnothing$
