To solve this system of equations, let's use the method of substitution or elimination:

We'll start with the substitution method. From the first equation, we can solve for y:

-2x + y = -5
y = 2x - 5

Now, we can substitute this expression for y in the second equation:

3x - 2(2x - 5) = 12
3x - 4x + 10 = 12
-x + 10 = 12
-x = 2
x = -2

Substituting this value of x back into the first equation, we can solve for y:

-2(-2) + y = -5
4 + y = -5
y = -9

Therefore, the solution to the system of equations is (-2, -9).

Hence, the correct answer is C. (-2, -9)(-2, -9).
