# How to have multiple rows on the left side of an equation

I have an equation whose left side has a long text. I would like to make it on multiple rows followed by the equal sign and then the right side.

\documentclass[12pt]{article}
\usepackage{amsmath}
\begin{document}

$$\text{The left hand side of this equation is very long} = a < x < b$$

\end{document}

This is what I want. The left side has two rows so that it's not too wide.
