Use Cramerʹs rule to solve the system of equations. If D = 0, use another method to determine the solution set.
-$$\begin{array} { l }
- 7 x + 92 = 9 y \
- 2 x - 6 y = - 40
\end{array}$$
A) $\{ ( 7,5 ) \}$
B) Cramer's rule does not apply since $D = 0 ; \varnothing$
C) $\{ ( 8,5 ) \}$
D) $\{ ( 8,4 ) \}$
