If your equation is not numbered, you can simply use \leqno:
$$
your equation
\leqno\blacktriangleright
$$
For numbered equations, the following does the trick
\def\triangleeq{%
\let\theeq\theequation
\def\theequation{\theeq
\rlap{\hskip -\displaywidth\ $\blacktriangleright$}}}
\begin{equation}
\triangleeq
your equation
\end{equation}
Just use the command \triangleeq inside the equation environment where
you want the triangle. The triangle will be placed at the beginning of
the line that has the equation number.
