Use Cramerʹs rule to solve the system of equations. If D = 0, use another method to determine the solution set.
-$$\begin{array} { r }
- 2 x - 6 y - z = - 18 \
x - 7 y + 8 z = 59 \
- 4 x + y + z = 1
\end{array}$$
A) $\{ ( 2 , - 1 , - 8 ) \}$
B) $\{ ( 1,8,1 ) \}$
C) $\{ ( 2,1,8 ) \}$
D) $\{ ( 3 , - 1,8 ) \}$
