Use Cramer's Rule to Solve the System of Equations $$\begin{array} { l } 2 x + 8 y + 4 z = - 16 \\x + 4 y + 2 z = 8 \\x + y + z = - 2\end{array}$$

Multiple Choice

Use Cramer's rule to solve the system of equations. If D = 0, use another method to determine the solution set.
- $$\begin{array} { l } 2 x + 8 y + 4 z = - 16 \\x + 4 y + 2 z = 8 \\x + y + z = - 2\end{array}$$

A) Cramer's rule does not apply since $D = 0 ; \{ ( 2 z - 1 , z + 2 , z ) \}$
B) $\{ ( 4,3 , - 2 ) \}$
C) $\{ ( - 2,4,3 ) \}$
D) Cramer's rule does not apply since $D = 0 ; \varnothing$
