insert equation in a list

Hi every one

I used to run winedt program which writing Latex with Acrobat reader but now it open with Gsview. I do not know what change it so could you help me for that?

And I have another problem when I insert equation in a list like (i), (ii) the equation stay under (i), (ii). as example,

\begin{enumerate}

\item

\begin{equation}\label{eq 1}

x+3=5

\end{equation}

\item

\begin{equation}\label{eq2}

3x=2

\end{equation}

\end{enumerate}

How could I make the equation in the same line ?

Thanks alot
