# Math Help - Solving for beta?

1. ## Solving for beta?

Hello,

Boy... its been a long time since I have done this stuff....

In any case, I am trying to solve for B in the following equation:

a = B/B+1

Therefore:

(B+1) a = B/B+1 (B+1)

(B+1) a = B

and now I am stuck!!!1

Any help is appreciated!

From where you ended up:

\displaystyle \begin{align*} (B + 1)a &= B \\ aB + a &= B \\ a &= B - aB \\ a &= B(1 - a) \\ \frac{a}{1 - a} &= B \end{align*}
