To repeat the equation use math macros: define a math macro whose name is
"myequation", and its definition is "y=2x", and then insert the formula
and type \myequation.
To repeat the numbers, insert a label into the first formula,
and then in the second one write \tag{\ref{<the label>
You also need to enable AMS math in the document dialog.
