Use Cramer's rule to solve the system of equations. If D = 0, use another method to determine the solution set.
-$$\begin{array} { c }
- 5 x + 2 z = - 26 \
7 x + 9 y + 4 z = 113 \
- 9 x - 6 y \quad = - 96
\end{array}$$
A) $\{ ( 7,2,7 ) \}$
B) $( \{ 7,5,2 ) \}$
C) $\{ ( 6,7,2 ) \}$
D) $\{ ( 6 , - 7 , - 2 ) \}$
