How do you manipulate Doppler's Equation in order to isolate Vw and Vs?

So the Doppler Equation is



Fd = ( (Vw) / (Vw + or - Vs) ) Fs



How would I manipulate this equation so I can find the values of the Vw ( Wave velocity) and Vs ( Source velocity).



I've already figured out how to manipulate to find the Source Frequency (Fs), but not these other two. Can anyone help me out?How do you manipulate Doppler's Equation in order to isolate Vw and Vs?Vw = +/- Fd Vs / (Fd - Fs)



Vs = (Fd Vw +/- Fs Vw) / Fd
