Rearrange algebra formula to make n the subject - GCSE Question

http://www.3minutemaths.co.uk/gcse-pr...

This video is all about how to rearrange an algebra formula to change the subject to 'n' and forms part of the playlist 'How to rearrange or change the subject of a formula.'

This question is around grade B / A at GCSE and there are some similar practice questions on http://www.3minutemaths.co.uk/. In this problem we're asked to make n the subject of the formula K = (3n + 2)/n+1. The easiest way is to multiply both sides by n+1 and go from there.

I hope the video helps and please do leave a comment - thanks!
