Use Cramer s Rule to solve for x in the following system. $\left\{ \begin{array} { l }
2 x - 6 y = - 8 \
2 x + 2 y = 7
\end{array} \right.$
A) $x = \frac { \left| \begin{array} { c c }
2 & - 8 \
2 & 7
\end{array} \right| } { \left| \begin{array} { c c }
2 & - 6 \
2 & 2
\end{array} \right| }$
B) $x = \frac { \left| \begin{array} { c c }
2 & - 6 \
2 & 2
\end{array} \right| } { \left| \begin{array} { c c }
- 8 & - 6 \
7 & 2
\end{array} \right| }$
C) $x = \frac { \left| \begin{array} { c c }
- 8 & - 6 \
7 & 2
\end{array} \right| } { \left| \begin{array} { c c }
2 & - 6 \
2 & 2
\end{array} \right| }$
D) none of these
