For simplicity, I will exchange $ for £
Now we group all terms with an N in them:
That's what I got, remember to switch the dollar sign for the euro sign. :P
How do I rearrange this formula to make 'N' the subject?
((1.86x£1-£1)xN)+((-£1)x(100-N)) = £7.88
I know that the parenthesis might not make complete sense, but this is a formula I am using in Microsoft Excel which works fine. At present I have values for 'N' which give me £7.88. There are other occasions where I have the £ value result, but do not know 'N'.
It's a long time since I have had to rearrange something like this. There are 2 N's which confuses me. Thanks in advance.
Thanks Aryth. That works great although I am finding it hard to understand how the the rearrangement rules work. I am also trying to re-arrange the formula to find 'T', but have not had any luck with that either.
Anyone have any ideas?
((Tx£1-£1)x58)+((-£1)x(100-58)) = £7.88
Thanks in advance.
