Rearranging formula
Hi,
I am struggling to rearrange the following formula:
........ ( A x (1 + G) )
 = B
(W + R  G) x (1 + W + R)
I need to rearrange so that it is W = [formula]
If anyone could provide a solution that would be great.
Thanks

Re: Rearranging formula
1) In your mind's eye, W is the only variable. Despite all those letters, think of everything else as a number, like 7 or 3, and manipulate it that way. It's just W and a bunch of numbers.
2) Clear fractions (i.e. multiply both sides of the equation by something that removes all fractions from both sides).
3) Multiply out and collect like terms (since it's just W and a bunch of numbers, "like terms" means "like Wterms").
4) Solve for W.

Re: Rearranging formula
After rearranging, you get a quadratic equation in W, not a straightforward equation. Remember what johnsomeone said above, and solve the quadratic and then, use the resulting formula as the formula with W as one side, and everything as other side.
