# Math Help - (Algebra) Just shifting around an equation

1. ## (Algebra) Just shifting around an equation

It's been way too long since I've done any algebra, so I'm hoping I can get a quick answer from you guys who are doing it every day.

x = (r-(i/g)) * .25 * b

I need to rewrite this in terms of b =

2. b=x/((r-(i/g))*.25) ?

That should not have taken 15 minutes.

3. $b=\frac{4*g*x}{g*r-i}$

$b=\dfrac{4gx}{gr-i}$
