Question 755497
Solve 3x-6y=12
           2x+6y=-12

By using elimination. Express your answer as an ordered pair.


3x-6y=12
+
2x+6y=-12
_________

5x=0
x=0

(Since the y's already canceled each other, I didn't have to multiply anything.)

Now plug the x-value in both equation and see if it works:

3(0)-6y=12
-6y=12
y=-2

2(0)+6y=-12
6y=-12
y=-2

So the answer is (0,-2)


Hope this helps!
