Use Cramer's rule to solve the system of equations. If D = 0, use another method to determine the solution set.
-$$\begin{array} { l }
9 x + 5 y = - 38 \
- 7 x - 2 y = 39
\end{array}$$
A) Cramer's rule does not apply since $D = 0$; $\varnothing$
B) $\{ ( - 8,6 ) \}$
C) $\{ ( - 7,6 ) \}$
D) $\{ ( - 7,5 ) \}$
