The \colorbox takes it out of math mode. I assume it is equivalent to 
something like \mbox on the inside. Compare:

  \documentclass[11pt]{book}
                \usepackage{color}                     
\usepackage{amsmath}
    \begin{document}

        \begin{center}
            2x=7
        \end{center}

        \begin{equation*}
            \colorbox{yellow}{2x=7}
        \end{equation*}

        \begin{center}
            \colorbox{yellow}{$2x=7$}
        \end{center}

        \begin{equation*}
            \colorbox{yellow}{$2x=7$}
        \end{equation*}


   \end{document}
