"Would Mulder and Scully solve [insert mystery from a non X-Files piece of media here]" is a deceptively complex question because there are two different answers depending on which version of the show our hypothetical episode is part of.
In the one version, Mulder and Scully wildly misunderstand the nature of the problem in diametrically opposite ways, and eventually succeed in removing the immediate threat in spite of having no idea what's going on, but do so in a way that traumatises everyone involved and ultimately reinforces the status quo, because law enforcement agencies are institutionally incapable of solving real problems even when their individual agents act with the best of intentions.
In the other version, Mulder pulls the correct solution out of his ass in the first five minutes, but can't prove it because the evidence keeps getting Phineas and Ferbed the moment before Scully walks into the room, and the problem is fixed forever by shooting a sewer man with a gun.
The trouble, of course, is that these are both describing the same show.
