Solve the System of Linear Equations by the Method of Elimination

Solve the system of linear equations by the method of elimination and identify the grey line in the graph with its linear equation. $\left\{ \begin{array} { c } 6 x - 6 y = - 48 \\x + 4 y = 12\end{array} \right.$

A) The solution is (-4,4) and the equation of the grey line is $6 x - 6 y = - 48$ .
B) The solution is (-4,4) and the equation of the grey line is $x + 4 y = - 20$ .
C) The solution is (-4,4) and the equation of the grey line is $6 x - 6 y = - 48$ ..
D) The solution is $( 4 , - 4 )$ and the equation of the grey line is $6 x - 6 y = - 48$ .
E) The solution is $( 4 , - 4 )$ and the equation of the grey line is $6 x - 6 y = - 48$ ..
