Find a+b+c?
Question asked by: amaljay
Asked on: 09 Feb 2010
This is too complicated for me but maybe one of the maths experts around here can solve it!
I think the key is to understand how to be able to re-arrange algebraic equations correctly.
It is worth getting someone good at maths to explain the method to you as once you've learned it you can apply it in every case.
