Use Cramerʹs Rule to Solve the System of Equations $$\begin{array} { l } x + 6 y = - 18 \\- 7 x + 5 y = 32\end{array}$$

Use Cramerʹs rule to solve the system of equations. If D = 0, use another method to determine the solution set.
- $$\begin{array} { l } x + 6 y = - 18 \\- 7 x + 5 y = 32\end{array}$$

A) Cramer's rule does not apply since $\mathrm { D } = 0$ ; $\varnothing$
B) $\{ ( - 7 , - 1 ) \}$
C) $\{ ( 6 , - 1 ) \}$
D) $\{ ( - 6 , - 2 ) \}$
