$\overline{){{\mathbf{M}}}_{{\mathbf{1}}}{{\mathbf{V}}}_{{\mathbf{1}}}{\mathbf{=}}{{\mathbf{M}}}_{{\mathbf{2}}}{{\mathbf{V}}}_{{\mathbf{2}}}}$

$\frac{{\mathbf{M}}_{{\mathbf{1}}}{\mathbf{V}}_{{\mathbf{1}}}}{{\mathbf{M}}_{\mathbf{2}}}{\mathbf{=}}\frac{\overline{){\mathbf{M}}_{{\mathbf{2}}}}{\mathbf{V}}_{{\mathbf{2}}}}{\overline{){\mathbf{M}}_{\mathbf{2}}}}\phantom{\rule{0ex}{0ex}}\phantom{\rule{0ex}{0ex}}{{\mathbf{V}}}_{{\mathbf{2}}}{\mathbf{=}}\frac{{\mathbf{M}}_{\mathbf{1}}{\mathbf{V}}_{\mathbf{1}}}{{\mathbf{M}}_{\mathbf{2}}}$
