 One is Arabic, one is Roman numbered.

To create this example, first a counter must be defined for the Roman numbered
 formulas.
 To do this the following is inserted to the LaTeX-preamble:
\end_layout

\begin_layout Standard

\series bold

\backslash
newcounter{rom}
\begin_inset Newline newline
\end_inset


\backslash
renewcommand{
\backslash
therom}{
\backslash
roman{rom}}
\end_layout

\begin_layout Standard
\begin_inset Newpage newpage
\end_inset

To save the value of the Arabic counter 
\series bold
equation
\series default
, this is added to the preamble
\end_layout

\begin_layout Standard

\series bold

\backslash
newcommand{
\backslash
c@org@eq}{}
\begin_inset Newline newline
\end_inset


\backslash
let
\backslash
c@org@eq
\backslash
c@equation
\begin_inset Newline newline
\end_inset


\backslash
newcommand{
\backslash
org@theeq}{}
\begin_inset Newline newline
\end_inset


\backslash
let
\backslash
org@theeq
\backslash
theequation
\end_layout

\begin_layout Standard
To be able to switch in the document between the two numbering schemes,
 the following commands are defined in the preamble:
\end_layout

\begin_layout Standard

\series bold

\backslash
newcommand{
\backslash
setrom}{
\backslash
let
\backslash
c@equation
\backslash
c@rom
\backslash
let
\backslash
theequation
\backslash
therom}
\end_layout

\begin_layout Standard
for Roman numbering and
\end_layout

\begin_layout Standard

\series bold

\backslash
newcommand{
\backslash
setarab}{
\backslash
let
\backslash
c@equation
\backslash
c@org@eq
\backslash
let
\backslash
theequation
\backslash
org@theeq}
\end_layout

\begin_layout Standard
for Arabic numbering.
\end_layout

\begin_layout Standard
Every formula will be by default numbered Arabic.
 To switch to Roman numbering, the command 
\series bold

\backslash
setrom
\series default
 is inserted in TeX-mode.
 With the command 
\series bold

\backslash
setarab
\series default
 the numbering is switched to Arabic.
\end_layout
