I'm trying to figure out the Thevenin equivalent as seen from the load of a wheatstone bridge… however, I think the model example in the book is wrong:
Here's what the book has to say:
Here's my work:
Which is the right answer?
Electronic – thevenin equivalence of wheatstone bridge load
circuit analysis

Looks like you are. They're making an algebraic error, assuming that adding conductances is the same as adding the associated resistances (initial equation is wrong). They further compound it by combining parallel resistors wrongly...the parallel resistances should each have their own reciprocol, not share the same denominator.
