x = 5/3

Explanation:

2(x-5)^-1 +1/x=0

Re-arrange the terms to have one fraction on each side.
(note that the negative index moves the bracket to the denominator)

x!=+5 and x!=0

2/(x-5) = (-1)/x " "larr"cross multiply"

2x = -x+5

3x = 5

x= 5/3

x = (5) / (3)

Explanation:

We have: 2 (x - 5)^(-1) + (1) / (x) = 0

The terms within the parentheses can be expressed as a fraction:

=> 2 cdot (1) / (x - 5) + (1) / (x) = 0

=> (2) / (x - 5) + (1) / (x) = 0

Let's combine the fractions:

=> ((2) (x) + (1) (x - 5)) / ((x - 5) (x)) = 0

=> 2 x + x - 5 = 0

=> 3 x = 5

=> x = (5) / (3)
