Homework Help: Algebra

Posted by Scott on Thursday, August 2, 2007 at 11:24am.

Simplify 1/r=1/x+1/y

Multiply both sides by rxy. Then simplify. I will be happy to check your work.

That is as compact and simple as the relationship can be written. Are you looking for an explicit formula for x, y or r?
