Well x and y have to be the same in both equations. Is there any possibility that those two equations will equal different numbers when they are the same?

Yes.

Subtract the equations. If you get a false statement, then there are no solutions.

anonymous · Answer

No, how can you have 2 equations that are the same give two different results? -3x+6y=-3x+6y so they have to have the same result or it's impossible.
