Still have absolutely no idea why i need to know this, i might just join the French Foreign legion and fight South American drug lords for the rest of my life because I hate algebra.

When the teacher teaches this subject for 5 lessons and this guy’s done it under 5 mins

Thank you so much for this video, I was literally just stuck on my assignment so o searched and since your thumbnail was a similar question, I chose it and used the same method to solve mine, its so easy .

My head is about to explode I’m only in year 7 and my maths teacher is giving me this. hard

[naimesiddique]

people 45 minutes of video on this topic where as he done less than 5 minutes you're truly awsome sir

Excellent video and you don’t skip steps..it really used to annoy me at school and elsewhere when the teacher assumed that you knew something and just skipped a step because he either didn’t know how to teach it or just to lazy. The trouble then is people like me with a particular difficulty with maths get totally lost because I try to understand in detail every step rather than just accepting the fact as true.

You just saved my grades, good sir.

Thanks Simon, this is indeed very helpful to me. In our school, instead of minusing thing, we move them to the other side and simply change the sign.

It's not the easiest to comprehend but somewhere to start for clues. Thanks for sharing your knowledge.

[hannahsowter]

0:57 At this point you can also cross-multiply! multiply k with (n+1) and k has an invisible denominator 1 which will be multiplied with (3n+2). I find this easier to understand but do what works for you!

I think there is another method when doing rearrangement u dont need multiply on both sides just simply drag the term from on side to another by changing the + or - sign but it is a very useful video . High-experienced and knowledgeable . 2 thumbs-up
