    I have a little question regarding a maths problem.


    Re-arranging formula is something I have always had difficulty with. Would someone be able to show me how to accomplish the following?

    If I had the following formula;

    a = xy / x + y

    But I wanted to make y the subject, how could I go about re-arranging that to get the desired outcome?

    Take out a common factor of y and divide through by the bracket i.e. factorise y and divide by the factorisation

    Multiply through by the denominator and expand. Get the y terms together and factorise

    Thanks guys, big help. You made me feel a bit thick for not already knowing that! Sometimes the most basic things trip me up.
