Use Cramer's Rule to Solve the System of Equations $$\begin{array} { l } - 7 x - 7 y = 14 \\- 4 x - 4 y = 8\end{array}$$

Multiple Choice

Use Cramer's rule to solve the system of equations. If D = 0, use another method to determine the solution set.
- $$\begin{array} { l } - 7 x - 7 y = 14 \\- 4 x - 4 y = 8\end{array}$$

A) $\{ ( - 2,0 ) \}$
B) $\{ ( - 2,1 ) \}$
C) $\{ ( - 3,1 ) \}$
D) Cramer's rule does not apply since $D = 0$ ; $\varnothing$
