[Tex/LaTex] How to shift one equation only towards the left margin

amsmathequationshorizontal alignmentmargins

  • I have an equation extending into the
    right margin and off the page.
  • I have many equations. For this
    equation only, I would like to shift

  • it to the left.

    MWE below.

    \documentclass[twoside]{book}                           
\usepackage{amsmath}                                      
     \begin{document}
        \begin{equation}
                \text{Some big equation}
        \end{equation}
\end{document}

Here is an example of an equation I wish to shift left horizontally as it is too far to the right.
