(4/x) – 5 = (5/2x)

Multiply both sides by 2x^2

(2x^2)(4/x) – 5(2x^2) = (2x^2)(5/2x)

8x – 10x^2 = 5x

8x – 10x^2 – 5x = 0

3x – 10x^2 = 0

x (3 – 10x) = 0

x = 0

0 is not an acceptable answer since if you plug it in the original equation, you will get division by 0 which is undefined.

3 – 10x = 0

3 = 10x

x = 3/10

This one works fine, I double checked it.

I hope this helped
