Best ResponseYou've already chosen the best response.2rewrite as \[y=\frac{x+3}{x2}\] and then either solve for x or switch x and y and solve for y. i will do it the second way

Best ResponseYou've already chosen the best response.2\[x=\frac{y+3}{y2}\] multiply to get rid of the denominator \[x(y2)=y+3\] multiply out on the left \[xy2x=y+3\]

Best ResponseYou've already chosen the best response.2put all the y's on one side \[xyy=2x+3\] factor out the y \[y(x1)=2x+3\] divide to get y by itself \[y=\frac{2x+3}{x1}\]

Best ResponseYou've already chosen the best response.2i mean it is it when you write \[f^{1}=\frac{2x+3}{x1}\]
