Students are having fun learning lyx and LaTeX, but some are bothered
that when they use double-spaced text, the display-math equations have
"too much space" around them. They want a single line equation to be
lined up on the ordinary double-spacing, with no extra vertical space.
LaTeX isn't really designed for double-spaced text. It's a typesetting
language. You can force it to do it, but, well, things can go funny. If
you really want more space, try 1.5 lines. That tends to work better.
Can you point us at the LaTeX magic to fiddle display math vertical
spacing in the article class?
The guide to all things math-mode is:

In your case, you want to see section 11.5, on vertical space.
