    I can't give you the answer... It may seem too easy for some, including me. Ok, here's an example;

    x + y = z

    Making x the subject of formula, we get

    x = z - y

    as if we subtracted 'y' from both sides

    Now;

    'y' subject of formula gives y = z - x

    Now, another one:

    xy = z

    Making 'y' subject of formula gives

    y = z/x

    as if we divided both sides by x

    And finally, you get the answer you're looking for. Post back your answer to see if you got it right.
