I'm working on finding inverse functions. I came across the following and the result is something I've struggled with for a long time. The function is:[math]f(x) = 2-5x[/math] and for the inverse I got:[math]\frac{x-2}{-5}[/math]However, the answer is given as:[math]\frac{2-x}{5}[/math]I know this is the answer I got multiplied by -1, but why and how can that be legal if we're not also multiplying the other side of the equation by -1?
