Use Cramer's rule to solve the system of equations. If D = 0, use another method to determine the solution set.
-$$\begin{array} { r }
x - y + 2 z = 3 \
5 x + z = 3 \
x + 5 y + z = 18
\end{array}$$
A) Cramer's rule does not apply since $D = 0 ; \varnothing$
B) $\{ ( 3,3,0 ) \}$
C) $\{ ( 0,3,3 ) \}$
D) $\{ ( 3,0,3 ) \}$
