    (6 - w)....(7w - 9)

    --------- – ------------

    (w - 8)......(8 - w) ------------- (8 – w) = – (w – 8)

    (6 - w)......(7w - 9)

    = --------- + ------------

    (w - 8)...... –(w - 8)

    (6 - w)....(7w - 9)

    = --------- + ------------

    (w - 8)......(w - 8)

    ( - 3 + 6w)

    ----------------

    (w - 8)

    (6w – 3)

    = -------------

    (w - 8)
