(0, -4)
You just need to substitute the answers given into the equation.
-3(0) + (-4) = -4
3(0) + (-4) = -4
Since both of these equations actually equal -4, then (0, -4) is the correct pair.

If we add the two equations together, we can eliminate the x variable, to yield:
2y = -8
y = -4.
When y = -4, x = 0.
Therefore, the simultaneous solution is (0, -4)

Add the two functions together to get 2y=-8 or y=-4.
So the solution is (x,y)=(0,-4).

-3(0)+(-4)=-4
0-4=-4
3(0)+(-4)=-4
0-4=-4
