We solve as follows:

-12x - 2y = 30

2(-4x + y = -5)

---------------------

-12x -2y = 30

-8x + 2y = -10

--------------------

-20x = 20 => x = -1

Now we replace the value of x in one of the original equations to solve for y, that is:

-4(-1) + y = -5 => 4 + y = -5 => y = -9

So, the solution is the point (-1, -9).
