I've checked out a similar question, but to the best of my knowledge, it only tells me that "Name et al." is used as a singular subject since it refers to the authors, but what if the reference of their article is followed by? I found the following sentence in a journal paper:

Gomes et al. [7] also outline a greedy method for finding feasible solutions...

So how should I use something like "et al. [1]" in the end? I'm really confused now.
