    Hi Sir, I was just wondering if the playlist you have on your website covers the whole further maths syllabus/specification? Also thank you so much for your videos they have been really helpful!

    • @1stClassMaths

      Pretty much. The topics missing are the ones on usual GCSE. I'd recommend if you do AQA regular maths to also check the rationalising denominator video (the second half as it has some harder questions).

    Will it work if instead of eliminating, I use substitution? For example, make a the subject in equation 2 and substitute that into 1

    how do you know whether to add or subtract the two equations?

    • @1stClassMaths
      @1stClassMaths  4 месяца назад +1

      You add if the signs of the varilable you are eliminating are different. Subtract if the same.

    Why did you use 3 to multiply the last equation 😢

    • @1stClassMaths
      @1stClassMaths  4 месяца назад +1

      On the final example? It is because on one equation we had b and another we had 3b so by multiplying by 3 we get a 3b in both of them. This means we can eliminate it.
