Hi guys,

i was wondering how i would go on about solving this:

$\displaystyle a=-5(5B-5) $

Is this solvable?

Yes, of course. That's a simple linear equation. To solve for B, you have to "unwrap" B, undoing what has been done to it.

Seeing that "-5" on the right, divide both sides by -5:
-a/5= 5B- 5.

Add 5 to both sides:
5- a/5= 5B

Finally, divide both sides by 5:
B= 1- a/25.
Thanks from topsquark and MathRookie
