(The numerical can also be used with many variables e.g. P*v=n*R*T etc.)

I'm a big fan of the numeric solver as well. As an added benefit, you can solve the function backwards. For instance if you have a desired Y value, you can enter it and solve for X (note you may have to play with an initial guess for X to find the right answer if there are multiple possibilities).
