In order to find which system has the ordered pair (-4, -12) as a solution, let's check this pair in each system.
We can see that the first two options have the function x = (1/3)y and the last two have the function y = (1/3)x.
Looking at the ordered pair, we have that x is 3 times smaller than y, therefore the correct equation is x = (1/3)y.
Then, the second equation has a constant value for the sum "x + y".
Calculating x + y using the coordinates of the ordered pair, we have a value of -16.
Therefore the correct equation is x + y = -16.
So the option that has the correct system is the second one.
