When writing a paper which applies some known method to a new problem, for completeness we may need to summarize that method, probably as a section on its own.

In the paper where it was first proposed, the method was described in a set of equations. In my case, I need to include some of these equations, because I need to refer to them in the subsequent part of my paper.

Currently I write something like the following:

We apply the X method [citation], which we shall summarize below, to describe ...

and then comes the equations, interspersed with some texts, which are paraphrased from the originals.

How do we give the proper attribution to the paper in which the method was first described, without giving the impression that some of the equations are our own? Is the above sufficient? Including [citation] before every equation seems awkward, since all of these equations are from a single paper.
