Problem Solving (PS) | If xy > 0, 1/x + 1/y = 5, and 1/xy = 6, then (x+y)/5 = ?

I am stuck trying to understand this explanation. I got the right answer, but not this way.

\(\frac{1}{x}+ \frac{1}{y} = 5\)
\((\frac{1}{x}+ \frac{1}{y}) = \frac{x + y}{xy}\)
Aren't the two RHS equivalent?


Can anyone explain the steps from the first part of the above sentence
...
