Sorry, I read the original post too quickly. I realize the issue is with
the space between the equivalence sign and the two sets of equations.
The problem is the use of the cases environment, which is inappropriate.
A better solution, with the amsmath package loaded, is the LaTeX code:
\begin{equation*}
\left\{
\begin{aligned}
x &= 1, \\
y &= x+2
\end{aligned}
\right.
\Leftrightarrow
\left\{
\begin{aligned}
x &= 1, \\
y &= 3.
\end{aligned}
\right.
\end{equation*}
(Sorry, I don't have the original equations at hand.)
I'm just learning LyX, so I'm not sure how much of the preceding can
readily be done without actually inserting everything directly as LaTeX
code.

When I viewed the dvi file, the size of the equivalence sign looked just
right.

Dear All,
I am trying to insert a system of equation in a LyX document. I am
using the cases environment, but, as you can see from the attached
example, the space between the first system of equations and the
equivalence symbol is too large and not symmetric regarding the
distance between the equivalence symbol and the second system of
equations. Any ideas about how to improve this?
Thanks, Murray. Unfortunately, here, even on the dvi file, the
equivalence symbol looks closer to the second system of equations than
to the first one.
