Find the inverse equations of the following:

1.

2.

So the equations become...

1.

2.

Sovle for .

I've played with the algebra a few different ways, especially on the rational function, but I still can't solve for 'y' in either equation! I've also graphed both functions, and they both appear to have an inverse (geometrically anyway).

Step-by-step algebra would be helpful - thanks!
