Math & Science ⇒ using subequations with columns

[lancekam]

I am typing a paper in which I would like to use subequations with 3 columns. I want the output to look like

w=4 (1a) a>b (2a)
x=a^2+b^2 (1b) a=2wt (2b)
y=c^2+d^2 (1c) where b=3ew (2c)
z=e^2+f^2 (1d) c=5 (2d)
q=t (1e)
Note:the 1a,1b,... are the subequation numbering (and I reference them later, so I need it to be the subequation numbering) and the "where" is centered. I cannot seem to get \begin{multicols} to accept subequations. I do not know how to get the "where" centered to where it is half way down in the second column. Any help would be much appreciated.

Thank you both so much. I am a little new to Latex and have yet to mess with minipage. Juanjo, your code works perfectly. It is exactly what I was looking for. Thank you so much. This is such a help.
