Best ResponseYou've already chosen the best response.27r6s=36 6r+7s=43 r = (36 + 6s)/7 r = (437s)/6 r = r 6(36 + 6s) = 7(43  7s) 216 + 36s = 301  49s 301  216 = 85s 85 = 85s 85/85 = s 1 = s

Best ResponseYou've already chosen the best response.2Because I eliminated r variable, then solved for s

Best ResponseYou've already chosen the best response.2It's just not elimination method you're used to. Besides, my methods get the correct answer. I can't really speak for the elimination methods you're used to.

Best ResponseYou've already chosen the best response.2I invented my way, that's why. If you use x and y as variables you'll see why.

Best ResponseYou've already chosen the best response.2I invented a plethora of approaches to math that make much more sense than methods taught in school. Some of which are pretty silly and potentially confusing.

Best ResponseYou've already chosen the best response.2You can prove it to yourself by plugging in r = 6 and s = 1 back into the original equations

Best ResponseYou've already chosen the best response.2The method I use, you've been taught it already.

Best ResponseYou've already chosen the best response.2y = mx+b If you have an equation with x and y on the same side, and you want to isolate y, say, for graphing reasons, you can do that. In this case, I isolated r, which would be y. I do this so that it's easier to solve systems of equations, also I can graph the equations I isolated on a graph to check them. So I'm doing two thing by using my method. I'm providing a way to check my answer graphically, and I'm finding an easier, simplier way to solve the more difficult systems of equation problems.

Best ResponseYou've already chosen the best response.0oh i already looked at what you did but to me its a lot like the susbstitution methos instead of the elimination method asked in the question

Best ResponseYou've already chosen the best response.27y6x=36 6y+7x=43 y = (36 + 6x)/7 <I graph this to check y = (437x)/6 <and this too y = y 6(36 + 6x) = 7(43  7x) 216 + 36x = 301  49x 301  216 = 85x 85 = 85x 85/85 = x 1 = x 6 = y

Best ResponseYou've already chosen the best response.0you must realize that some instructors would want to see that problem done by instruction instead of substituting for r

anonymous

Best ResponseYou've already chosen the best response.0but im not arguing, just making an observation

Hero

Best ResponseYou've already chosen the best response.2I would argue that I did eliminate one variable while solving.

anonymous

Best ResponseYou've already chosen the best response.0what you did was solve each equation for r then set them equal

Hero

Best ResponseYou've already chosen the best response.2Either way, no one has yet to post the solution you're looking for.

Hero

Best ResponseYou've already chosen the best response.2I figure that maybe you would but instead you want to argue with me.

Best ResponseYou've already chosen the best response.0well im justsaying what you did is almost the exact definition of the substitution method

Hero

Best ResponseYou've already chosen the best response.2I posted my solution because I don't care much for the elimination method as you know it.

Best ResponseYou've already chosen the best response.2I posted a solution since no one had posted one yet. And by technicality, I did indeed eliminate r variable by substitution.

Best ResponseYou've already chosen the best response.0if they had asked them to do it susbstitution method, you answer is absolutely correct

Best ResponseYou've already chosen the best response.2If it has to take an hour to post the solution, I'd rather stick with my methods...

anonymous

Best ResponseYou've already chosen the best response.0well just realize there are two methods and when it asks you do do it that way for college per say, then the other method would be wrong

anonymous
