Use Cramer's Rule to Solve the System of Equations $\begin{array} { l } 2 x + 8 y + 8 z = 24 \\x + 4 y + 4 z = - 4 \\x + y + z = - 6\end{array}$

Multiple Choice

Use Cramer's rule to solve the system of equations. If D = 0, use another method to determine the solution set.
$\begin{array} { l } 2 x + 8 y + 8 z = 24 \\x + 4 y + 4 z = - 4 \\x + y + z = - 6\end{array}$

A) Cramer's rule does not apply since $D = 0 ; \varnothing$
B) Cramer's rule does not apply since D}=0 ;{(2z - 1, z+2, z) }
C) {(-1,5,-6) }
D) {(-6,-1,5) }
