Question

Solving Equations Using Reciprocals
can someone help me understand how to do this exactly?..

Answer 1

Something specific would have been better. Anyways, let me know if this is helpful.

Suppose 1/z= 1/x+1/y

you can solve the rhs = 1/x+1/y i.e. x+y/xy

and cross multiply with 1/z

So

z(x+y)=xy

zx+zy=xy
