You don't say what you want to do with this expression, so I'll just assume you want to add and simplify.

%28x+%2F+%28x+-+3%29%29++%2B++1+%2F+3

Step 1: Determine your LCD. Since x-3 and 3 have no common factors, the LCD is simply:

3%28x-3%29

Step 2: Apply the LCD to each fraction:

%283x%2F%283%28x-3%29%29%29%2B%28x-3%29%2F%283%28x-3%29%29

Step 3: Add the numerators:

%283x%2Bx-3%29%2F%283x-9%29

Step 4: Combine like terms:

%284x-3%29%2F%283x-9%29
