New Posts For Thread: Maths equation help?https://community.betfair.com/general_betting/go/thread/view/94082/29155721/maths-equation-helpHi, I have an equation in my study book which goes as follows:1. 8 = x + 1.2(7-x)2. 8 = x + 8.4 - 1.2x3. 0.2x = 0.44. x = 2Can anyone tell me how on earth they get from stage 2 to stage 3?Many thanksYes, thanks a lot guys. I can remember learning equations at primary school and I didn't understand them then - one of my mates told me an easy way was that if x= yz you just put numbers in so that it becomes 6=3 x 2, then you can switch the numbershttps://community.betfair.com/general_betting/go/thread/view/94082/29155721/maths-equation-help?post_id=520445121#520445121Yes, thanks a lot guys.

I do need to study them as it's for an exam, and they seem to assume you can do equations already - I've been looking them up and it's actually pretty easy I think I'm getting there. Thanks again - I wish I'd paid attentionhttps://community.betfair.com/general_betting/go/thread/view/94082/29155721/maths-equation-help?post_id=520378033#520378033Many thanks for your help.

I still don't really get it - I probably need to study equations.Thanks very muchhttps://community.betfair.com/general_betting/go/thread/view/94082/29155721/maths-equation-help?post_id=520372815#520372815Thanks, that was a very quick reply.
