Write equations in horizontal mode

I want to write equations numbered and horizontally like this.
Thank you for your help.

Thank you for your answer. This is what I did:

\documentclass[12p]{article}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{graphicx}

\begin{document}
\begin{tabular}{ l c r }
$2x+3=7$ & $5x-2=3$ & $2x+7=11$\\
$6x+1=9$ & $6x+1=9$ & $-4x-5=14$ \\
$2x+3=7$ & $5x-2=3$ & $2x+7=11$ \\
\end{tabular}
\end {document}

And it produced This.

Now, How would I do to number them automatically with a bold font?
Also, how would I do to increase horizontal spaces?

aaa

I enhanced a little the equations, but still the numbering increases vertically instead of horizontally:

\documentclass[12p]{article}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage{multicol}
\begin{document}
\begin{enumerate}
\begin{multicols}{3}
\item $2x+3=7$
\item $5x-2=3$
\item $2x+7=11$
\item $9x-1=4$
\item $6x+1=9$
\item $-4x-5=14$
\item $2x+3=7$
\item $5x-2=3$
\item $2x+7=11$

\end{multicols}
\end{enumerate}
\end{document}

To increase spacing, try \quad. Thanks from Mohajir Last edited by greg1313; August 26th, 2015 at 03:48 PM.
