Best ResponseYou've already chosen the best response.0if the equation is y=x+5/7 to do that you just need to subtract 5/7 on both sides if the equation is y=(x+5)/7 I would first multiply 7 on both sides and if is this equation you have one more step remaining after that Here is an example: \[y=x+a \\ \text{ Subtract } a \text{ on both sides } \\ ya=x \\ \text{ or other way around } x=ya \\ \text{ then you can interchange } x \text{ and } y \\ y=xa \text{ this is the inverse of } y=x+a\] it appears you multiply 5/7 on left hand side y5/7=x? yes your a=5/7 \[y=x+\frac{5}{7} \\ \text{ subtract} \frac{5}{7} \text{ on both sides } \\ y\frac{5}{7}=x \\ x=y\frac{5}{7}\] yep now just interchange x and y replace x with y and y with x y= x+5/7 switch the x and the y and then solve for y \[y=x\frac{5}{7}\] you can solve for x then switch but either way here is another example of finding inverse of a linear function \[y=\frac{x+5}{7} \\ \text{ multiply both sides by } 7 \\ 7y=x+5 \\ \text{ then subtract} 5 \text{ on both sides } 7y5=x \\ \text{ now interchange } x\text{ and } y \\ 7x5=y \\ y=7x5 \text{ is the inverse of } y=\frac{x+5}{7}\]
