Prevent display math from creating a new line at the start of an item?

Question

\begin{description}
\item[xyz] \[x=y\]
\end{description}

x=y appears on the line below xyz, if I changed \[x=y\] to some normal text it wouldn't create the new line. How can I stop it?

Answer 1

\documentclass{article}
\everymath{\displaystyle}
\begin{document}
\begin{description}
\item[xyz]$x=y$
\end{description}
\end{document}

Edit

Based on the given comment.

\documentclass[preview,border=12pt]{standalone}
\everymath{\displaystyle}
\newcommand\myitem[2]{\item[$#1$]\hfill$#2$\hfill\null}
\begin{document}
\begin{description}
\myitem{xyz}{\frac10+0^0}
\myitem{\frac10}{0^0}
\end{description}
\end{document}

For those who dislike \everymath

\documentclass[preview,border=12pt]{standalone}
\newcommand\myitem[2]{\item[$\displaystyle#1$]\hfill$\displaystyle#2$\hfill\null}
\begin{document}
\begin{description}
\myitem{xyz}{\frac10+0^0}
\myitem{\frac10}{0^0}
\end{description}
\end{document}
