Homework Help: Have I rearraged this formula correctly?

  1. Jan 8, 2010 #1
    This formaula has to be rearraged to make X the subject:

    Y = A(X x B) / X-C

    My attempt is:

    X = AB - C / Y - A

    First of all, is it

    [tex]y = \frac{a(x \times b)}{x-c}[/tex]


    [tex]y = \frac{a(x \times b)}{x} - c[/tex]

    When you ask such questions it is better to use too many parentheses than not enough.

    Also, it's not a good idea to use X for multiplication when you have a variable named x.
