Hi guys, i was wondering how i would go on about solving this: $\displaystyle a=5(5B5) $ 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.
