directrix · Answer

2x - 3y = -12 -->                     2x  -3y   = -12
 x   - y  =    4 --> by -2  -->  -2x  +2y  =  -8
------------                         ----------------
                                                          -y =   -20
You did not state a preference.             y = ?      Then, find x.

I would choose to multiply the second equation by -2 and the add the components.

This is the Additon method.
