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.

Hi there,

Did you try with minipage???

The following code may help you:

Code: Select all

\begin{minipage}{0.3\textwidth}
  \begin{subequations}
  \begin{align}
    w&=4, \\
    x&=a^2+b^2, \\
    y&=c^2+d^2, \\
    z&=e^2+f^2, \\
    q&=t,
  \end{align}
  \end{subequations}
\end{minipage}%
\hfill where\hfill
\begin{minipage}{0.3\textwidth}
  \begin{subequations}
  \begin{align}
    a&>b, \\
    a&=2wt, \\
    b&=3ew, \\
    c&=5.
  \end{align}
  \end{subequations}
\end{minipage}

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.
