It sounds like this is rather simplistic, using additions and subtractions to isolate the unknown on one side of the equals sign, and using exact inverses to get it to its bare form. Is that really all there is to it? Is this documented anywhere?

This is described in details in the 27S/19B Technical applications book.
This will happen only if the unknown appears formally only once in the equation. So you can force iterative solutions by writing something like X+0*X rather than just X. Yes direct solutions are basic and straightforward, since the Pionniers are RPL-based a bit of RPL symbolics were embedded in them, but not much.
