Best ResponseYou've already chosen the best response.0Okay, let's try and solve the system of equations by using elimination. How many times does the second equation go in the first?

Best ResponseYou've already chosen the best response.0Put the equation side by side one another. What do you have to multiply with x to turn into 2x? What do you have to multiply with y to get 2y and what do you have to multiply with 9 to get 18? 2x + 2y = 18 x + y = 9

Best ResponseYou've already chosen the best response.0Multiply the second equation by 2 then. 2(x + y = 9) It'll equal the first equation. If the second equation and the first equation are equal, what does that mean?
