Use Cramer's Rule to Solve the System of Equations $$\begin{array} { c } x + 3 y = - 12 \\4 x + 4 y = - 16\end{array}$$

Multiple Choice

Use Cramer's rule to solve the system of equations. If D = 0, use another method to determine the solution set.
- $$\begin{array} { c } x + 3 y = - 12 \\4 x + 4 y = - 16\end{array}$$

A) $\{ ( 0 , - 4 ) \}$
B) $\{ ( 4,0 ) \}$
C) $\{ ( 1 , - 5 ) \}$
D) Cramer's rule does not apply since $D = 0 ; \varnothing$
