(5)/(x)  (2)/(x3) = 0
5(x3)  2(x) = x(x3)
5x152x = x^2 3x
3x15 = x^2 3x
this is where i get stuck please help thanks

Let's try it differently.
5/x = 2/(x3)
5x  15 = 2x
3x = 15
X = 5

Peter, anything multiplied by zero is still zero,
so your second line should have been
5x152x = 0
Now you have the same as what MatssRiceBowl has in the method he suggested.
