solve by the elimination method 3x-2y=0 -3x-y=-18

Question

mathteacher1729 · Answer

The second equation says y = -3x + 18 

So input that into the first equation and solve for y.  

Once you have the value for y, put that into either equation and solve for x. :)

anonymous · Answer

it's easier to put it on top of each other so you can see the positive's and negatives

3x-2y=0
-3x-y=-18

Cancel out -3's, and so you would have -3y=-18.

y=6. 

Substitute 6 into original equation.

And mathteacher, he asked for elimination, not substitution.
