Final answer:

The system of equations is solved using the elimination method, yielding the ordered pair (-4, 5) as the solution.

Step-by-step explanation:

Using the elimination method to solve the system of equations, we want to find the correct ordered pair that satisfies both equations. We have:

x - 3y = -19 (1)

2x + y = -3 (2)

Firstly, we multiply equation (2) by 3 so we can eliminate y by adding it to equation (1):

6x + 3y = -9 (2')

Now we add equations (1) and (2'):

x - 3y + 6x + 3y = -19 + (-9)

7x = -28

Divide both sides by 7:

x = -4

With x found, we can substitute it back into one of the original equations to find y. Let's use equation (2):

2(-4) + y = -3

-8 + y = -3

Add 8 to both sides:

y = 5

Thus, the correct ordered pair is (-4, 5).
