Problem with equation numbering

I'm writing my thesis using latex. I get a problem with equation numbering an

Minimal working example:

\documentclass{article}
\usepackage{refcheck}
\usepackage{hyperref}
\begin{document}
$$\label{equ1} H(x)=w^T+b$$
\end{document}

• Please create a minimal working example. Nobody is going to download your entire thesis, especially given the need to enter a captcha and unpack a rar file. (Yes, I did go to have a look.) – Harald Hanche-Olsen Apr 9 '16 at 9:53
• I have uploaded the entire thesis because the problem is due to the thesis style. The problem appears just with my thesis, when I use an article style I can get equation numbering correctly without problem – user2873476 Apr 9 '16 at 10:05
• Against my better judgment, I went and had a look (guess I am having a slow day). The problem appears with the article class too. I am going to edit your question now, adding a minimal working example. – Harald Hanche-Olsen Apr 9 '16 at 11:05
• thank for your example :) I have complicated the task with my long question – user2873476 Apr 9 '16 at 11:52

This is almost the intended result of the refhcheck package. I say almost, for instead of {?} you should be seeing ?equ1? in its place, indicating the label for that equation. But the hyperref package messes that up for you. You can just do
\usepackage[noref]{refcheck}

or just live with this output, but remember to remove the refcheck package before creating the final version of your thesis.
