Can anyone solve this equation?
Change the subject of the equation to R.
1 over R = 1 over x + 1 over y

is your formula supposed to say:
[s]1/R = 1/r +1/r?
In which case it would be:
1/R = 2/r
r = 2R
R = r/2[/s]
ah, you've edited

1/R = 1/x + 1/y
1/R = (x+y)/xy
R = xy/(x+y)

Stoner has the correct answer

1/R = 1/x + 1/y
R = 1/(1/x + 1/y)

xR3i = 3ix/(1/x + 1/y)
