Answer:

The solution would be (10, -3)

Step-by-step explanation:

In order to solve using elimination, multiply the top equation by -3 and then add the equations together.

-9x - 12y = -54

9x - 5y = 3

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

17y = -51

y = -3

Now that we have a value for y, we can put it into either equation and solve for x.

3x + 4y = 18

3x + 4(-3) = 18

3x - 12 = 18

3x = 30

x = 10
