Best ResponseYou've already chosen the best response.0for the second equation \[y=2x13\] you already solved for y. plug that y into the first equation, giving you\[2x(2x13)=11\]

Best ResponseYou've already chosen the best response.1So chrismoon, you are instructing the asker to ignore the directions which say to solve using elimination?????

Best ResponseYou've already chosen the best response.0ALl I just want to know is just how to flip it. and thats it.

Best ResponseYou've already chosen the best response.1@mariannu Do what I said and then add the two equations to eliminate y from the system

Best ResponseYou've already chosen the best response.0So its y + 2x = 11???

Best ResponseYou've already chosen the best response.0Ok that makes more sense thank you! ^.^ for the help. So I just do that for other equations like that right?

Best ResponseYou've already chosen the best response.0You're given two things: Equation 1)\[2xy=11\]Equation 2) \[y=2x13\] Equation 2 tells you what y is already. You can put what y equals (2x13 in this case) into the first equation for y. Equation 1 goes from \[2xy=11\] to \[2x(2x13)=11\] since\[y=2x13\] Simplify your Equation 1 from \[2x(2x13)=11\] to \[2x+2x+13=11\]giving you \[4x=24\] divide both sides by 4 to solve for x \[x=6\] Now that you have solved for x, go all the way back to the original Equation 2\[y=2x13\] Since we know what x is now, plug it in\[y=2(6)13\]giving us \[y=1\] There you have it: \[y=1\]and \[x=6\]

Best ResponseYou've already chosen the best response.1@chrismoon Why do you keep telling the asker to ignore the directions given?

Best ResponseYou've already chosen the best response.0Sorry, didn't see you guys already talked about it before I posted. Didn't get notified you guys got it taken care of.

Best ResponseYou've already chosen the best response.1@chrismoon The problem says to solve by elimination. You keep telling the asker to use substitution.
