Multiple Choice

Provide an appropriate response.
-For a certain system of two linear equations, the solution set is $\{ - 3 , - 6 \}$ , and $D = 18$ . Find the values of $D _ { X }$ and $\mathrm { D } _ { \mathrm { y } }$

A) $\mathrm { D } _ { \mathrm { x } } = - \frac { 1 } { 6 } ; \mathrm { D } _ { \mathrm { y } } = - \frac { 1 } { 3 }$
B) $\mathrm { D } _ { \mathrm { X } } = - 3 ; \mathrm { D } _ { \mathrm { y } } = - 6$
C) $\mathrm { D } _ { \mathrm { x } } = - 54 ; \mathrm { D } _ { \mathrm { y } } = - 108$
D) $\mathrm { D } _ { \mathrm { X } } = - 108 ; \mathrm { D } _ { \mathrm { y } } = - 54$
