Best ResponseYou've already chosen the best response.0Since the value of y in the first equation is 2, we can multiply the opposite of 2 to the second equation to eliminate y. So what is the opposite of 2?

Best ResponseYou've already chosen the best response.0What is the yterm of the second equation? It is just y. When you add 2y to 2y you get zero and the yterms will be eliminated. If you multiply the second equation by 2, the yterm of the second equation will become 2y. Then when you add equations, the yterms will be eliminated.
