So how to put the horizontal fill immediately after the displayed equation? I mean, I want the "(equation 1)" to be in the same line as the displayed equation. How should I do that? Guys please help! Thx!
I clicked "View" then "Source Pane" and it appears a window with the following Latex codes:
\[
1+1=2
\]
\hfill{}(equation 1)
I want to make my displayed equation look like the following one, where the text (the conclusion mark here in the picture) is in the same line as the equation, and it's at the right end. Lyx wouldn't allow me to do so. Whenever I insert a horizontal fill right after the displayed equation, after I press enter, it will automatically move the horizontal fill to the next line, and that's my problem.
\documentclass
and ending with\end{document}
that demonstrates the problem. – barbara beeton Aug 8 '15 at 12:20
