    Question A Problem in Ratios

    His this is an example problem from hall and knight's higher algebra book,
    it says

    if $\displaystyle x/l(mb+nc-la) = y/m(nc+la-mb) = z/n(la+mb-nc$)

    then prove that

    $\displaystyle l/x(by+cz-ax) = m/y(cz+ax-by) = n/z(ax+by-cz)$

    can you please tell me the steps one should go through to prove this?
