Multiple Choice

Solve the problem.
-Find $C$ and $D$ so that the solution set to the system is $\{ ( - 4,2 ) \}$ .
$$\begin{array} { l } C x - 2 y = - 16 \\2 x + D y = - 16\end{array}$$

A) $C = - 4 ; \mathrm { D } = - 3$
B) $C = 3 ; \mathrm { D } = - 4$
C) $C = - 3 ; \mathrm { D } = 4$
D) $C = - 4 ; \mathrm { D } = 3$
