have you learned substitution and/or elimination methods?

We can solve this by using a method called elimination. You could use substitution too, but sometimes elimination makes life a bit simpler. Plus, students tend to lean away from elimination, but with practice it can be better the sub. We can multiply the top equation by -5. This gives us -5x + 10y = -15 5x + 3y = 2 13y = -13 y = -1 Now plug that sucker back into any of those equations and solve for x :)

Sorry -- In the middle step, I added the two equations.
