(5)/(x) - (2)/(x-3) = 0

5(x-3) - 2(x) = x(x-3)
5x-15-2x = x^2 -3x
3x-15 = x^2 -3x

this is where i get stuck please help thanks

Let's try it differently.

5/x = 2/(x-3)
5x - 15 = 2x
3x = 15
X = 5
Peter, anything multiplied by zero is still zero,
so your second line should have been
5x-15-2x = 0

Now you have the same as what MatssRiceBowl has in the method he suggested.
