## math>philosophy Group Title How do I reference an {equation} with the same equation number later in the document? I have: \begin{equations} \begin{align} y = mx + b \end{align} \end{equations} And it shows that it's equation (1) in my document. How do I repeat that same equation later in my document after other equations with the same equation number (1)? one year ago one year ago

maybe you could copy the latex code from the equation and pate it in there later

2. math>philosophy Group Title

I did but then it shows the equation number as something else like (5) or something

 \label{eq1} \begin{align} y = mx + b \end{align} \end{equations}  By adding the \label{eq1}, you can later type \ref{eq1} and it should reference your equation

Those question marks should be \ref{eq1}.
