    simplify the following expression? (easy!)

    I know it must be simple, but I just can't get it It's only the first step of a large question, so if you get me started i would be vury grateful indeed!



    p.s: i know i have to merge the equation on the left by making a common denominator. i did it and then i flipped the second equation so it could be multiplied by the first, but the answer i get isn't what my friends say they have gotttennn......

    \displaystyle \frac{\frac{1}{x+2} + \frac{1}{x-4}}{\frac{(2x-3)(x-1)}{(x-4)(x+2)}}

    \displaystyle \frac{\frac{(x-4)-(x+2)}{(x+2)(x-4)}}{\frac{(2x-3)(x-1)}{(x-4)(x+2)}}

    first two steps ... finish it.
