Dear Maths Videos for web - free A Level Maths Videos- I find your video to be a huge help in my mathematics but what i do want to know is that at 3:04 why did you use 5 for the Fourth equation and 2 for the fifth equation? An urgent response would be helpful. Thankyou! :) Keep doing what you're doing!

Dear Mr what if we don't have the same coefficient.

Hi @Varsh Doobay, for some reason I'm not able to respond directly to your question, but here is my response... What we have to do is create 10y in both equations so that we'll be able to subtract 10y from 10y and isolate x. We need to isolate x in order to find its value.
