Best ResponseYou've already chosen the best response.03x + 2y= 2 4x + y= 4  y = 4x  4 3x + 2(4x  4) = 2 3x 8x  8 = 2 5x = 10 x = 2 3(2) + 2y = 2 6 + 2y = 2 2y = 8 y = 4 (2,4)

Best ResponseYou've already chosen the best response.0the difference is I subtracted the equations. I didn't add them.

Best ResponseYou've already chosen the best response.0You can do either. You might want to properly educate yourself on the topic before you start calling people out.

Best ResponseYou've already chosen the best response.0i already did the substitution method juss sayin'

anonymous

Best ResponseYou've already chosen the best response.0before you finish. my answer was x = 2 and y = 4 as shown above. So you are going to tell me that is incorrect?

anonymous

Best ResponseYou've already chosen the best response.0ChrisV you can always expand your horizons. Yes you can multiply by 2 then add, But you can just as easily and correctly multiply by +2 and then subtract. The fact that you can eliminate by both adding or subtracting is something you should put in your "solving" tool box.

Best ResponseYou've already chosen the best response.0You are missing the point: 3x+2y=2 (8x+2y=8)  5x = 10 x=2

Best ResponseYou've already chosen the best response.0why not call it the subtraction method then? The point is to multiply by a value that eliminates a variable

Best ResponseYou've already chosen the best response.0Just tryinying to sho the simplest way i guess, but yes that comes out correct too

Best ResponseYou've already chosen the best response.0anyways lets do something else lol, nothing more to argue about here. Just gonna disagree anyways

Best ResponseYou've already chosen the best response.0Yes that is true, and you may eliminate it either by subtracting or adding depending on your choice of the sign of your multiplier. I am not saying you are wrong and if you wish to restrict your mode of operation to always adding, then have at it.

Best ResponseYou've already chosen the best response.0not adding its called multiplication

Best ResponseYou've already chosen the best response.0lol Chris, maybe when you further your actual understanding of what it means to execute the elimination method then talk to me. Go ask any knowledgeable math teacher or professor you have ever had. I don't appreciate being told that I'm wrong when clearly, I am not. I'm not at all saying what you did was wrong but the fact that you have the inability to realize that the elimination method has multiple execution techniques and then accusing EVERYONE else of being wrong is just disrespectful. I'm sure you are a smart guy but you need to expand your horizon. I have been doing a lot of math for a very long time now. Good luck in the future.
