not all symbols exists in a bold version.
Try:
\usepackage{bm}
\bm{\beta}
\bm will simulate bold if needed.
BTW: \mathbf does not work on symbols anyway, only uppercase greek letters
(which is why the bm package is recommended)

I don't quite follow, are you looking for a way to simply have a few
matrices and an equation number?
(assuming the amsmath package)
\begin{equation}
\begin{pmatrix}
a_{11} & a_{12} \\ a_{21} & a_{22}
\end{pmatrix}
\begin{pmatrix}
b_{11} & b_{12} \\ b_{21} & b_{22}
\end{pmatrix}
=
\begin{pmatrix}
b_{11} & b_{12} \\ b_{21} & b_{22}
\end{pmatrix}
\end{equation}
