To solve this with elimination, if we look at these a +6 and a -6. If we added these directly the way they are, we'd get the Y's to cancel and we'd get 6X equaling -6 or X equal -1. Now to get rid of the X's, if we thought about looking at this top equation and multiplying it by a -2. If I multiply that entire equation through by a -2, I get -4 X -12 Y equaling -80, the second equation. If I leave exactly the same, we would then have additive inverses on the X terms so that when I add those two equations, the XS go away, so we get -18 Y equaling -126. If we divide each side by -18, we get y = 7, so our solution is -1 seven. This is going to be consistent because there's one solution, or at least one solution, and in dependent.
