(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
