it makes n sense how you got from 4x+3(5x+3) to 4x+15x+9
-
How do you solve it if it's ate up like
2x+5y=8
3x+2y=-10
????
-
omg thank you so much, you make it easier to understand, my math teacher is this lazy guy who cant write properly, he doesn't explain, he just expects us to understand it straight away
-
it has helped me a lot in understanding how to solve simultaneous equations!
-
@timur121997 hun, he got 38 because 4x+15x +9=47 so basically where it says +9 you minus 9 from 47 as you have to do the opposite hence 47-9=38. Hope ive helped :)x
-
how did you get 38?
-
If only i had you as my teacher. you'd teach the whole unit in 1 hour.
-
good explanation, like the video. Keep it up

I can't believe It has reached the point where I am learning more maths on YouTube than in actual maths class.
