@sheen4866 he brings the 20 over so it makes a minus and then does 3y=17-20
-
wait so i've spent like 10 hours working on this with my teacher and you have taught this to me in minutes... fuck...
-
how do you get 3y= -3?
-
you just rearrange the equitation... like 2y + x=12, if that's what you mean, or a single x=1x, its just easier to not write 1x... and simply x

@sladkoCCCC Firstly it was actually 108 not 180. Secondly it is just 36 multiplied by 3. He got this after multiplying the whole of equation 2 by 3, and if you multiply the equation you also have to multiply the answer.
