Write equations in horizontal mode

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

Define a table that doesn't have any borders.

$\displaystyle \begin{array}{ l c r }
1 & 2 & 3 \\
4 & 5 & 6 \\
7 & 8 & 9 \\
\end{array}$

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}

Use \textbf{...} for bold font. To increase spacing, try \quad.
Thanks from Mohajir

Math Focus: Calculus
You could also use the matrix structure:

Code:
\begin{document}

\begin{equation*}
\begin{matrix}
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{matrix}
\begin{equation*}

\end{document}
Which produces:

$\displaystyle
\begin{matrix}
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{matrix}
$
