5x%2F%2810x-20%29+-+10%2F%2810x-20%29

Since both the denominators are the same,
we can combine the numerators over the common 
denominator:

%285x-10%29%2F%2810x-20%29

Factor 5 out of the numerator and 
factor 10 out of the denominator:

%285%28x-2%29%29%2F%2810%28x-2%29%29

Cancel the (x-2)'s:

%285%28cross%28x-2%29%29%29%2F%2810%28cross%28x-2%29%29%29

5%2F10

Reduce the fraction:

1%2F2
