Best ResponseYou've already chosen the best response.0Hello! Is it \[f(x)=\frac{ 2x+3 }{ 5 }\] or \[f(x)=2x+ \frac{ 3}{ 5 }\]?

Best ResponseYou've already chosen the best response.0So you already switched x and y like this? \[ x=\frac{ 2y+3 }{ 5 }\]

Best ResponseYou've already chosen the best response.0Do you mean \[2y = 5x + 3\]

Best ResponseYou've already chosen the best response.0Yes, but it should be \(2y = 5x  3\). :) Now divide both sides by 2, and that's it.

Best ResponseYou've already chosen the best response.0\[y= \frac{ 5x3 }{ 2 } \] or \[y=\frac{ 5x }{ 2 }\frac{ 3 }{ 2 }\]

Best ResponseYou've already chosen the best response.0Oh, you can write it either way I put it, but it is not \(y=5x\frac{ 3 }{ 2 }\).

Best ResponseYou've already chosen the best response.0I know i meant to do \[y = \frac{ 5x  3 }{ 2}\]
