The units will not agree.
Also, just give some values to x and y and test the two versions.

Regarding the question about algebra conceptual physics course, the
other monkey wrench in the works is that some of the students, I would
estimate about a third of them, will already be quite good at algebra.

On a related note, what do you do to convince a person in  a lasting
manner that the reciprocal of (1/x + 1/y) is not, in general, x+y?
