Answer:
The solution would be (6, 2)
Step-by-step explanation:
In order to solve this using elimination, simply add the two equations together.
2x + 3y = 18
3x - 3y = 12
-----------------
5x = 30
x = 6
And now that we have the value for x, we can solve for y.
2x + 3y = 18
2(6) + 3y = 18
12 + 3y = 18
3y = 6
y = 2
