you working out so much in your head and not explaining properly where you getting these numbers from....

[oluwadunsin]

Guys I got confused too so I’m gonna leave this comment to help; Khan academy always makes things look more difficult that not is, just forget the whole 8x20 and 8x3 nonsense and instead just do
8-85/13 and that still gets you the same answer of 19/13

Hope this helped peace ✌🏾

where did he get 80 and 24 at 1:23 ? so

[ChewVodka]

I loved the way you explained it. But there is a simpler way to do it with the equation y-y1=m(x-x1) i will use the example you gave. m=17/13 and y1=8 and x1=5. Inputting those would be y-8=17/13(x-5) and you would solve it like a regular equation and end up with y=17/13x+19/13 :) just a tip.

He got 104 when he was converting 8 into an improper fraction in order to solve 8 - 85/13.
8 x 13 =104.
104/13 - 85/13 = b and so on and so forth...

This helped but Im wondering if for explanation purposes, would it be easier for people to understand, if you used numbers that are easier for people to work with, instead of these ridiculous fractions

[vmr]

How did you get the 104 and how did you get the 24...? So confusing

[catalinasalinas]

from where did he get the 24? i didn`t understand that???

[greyreaper]

Thx u so much, u can always turn something completely indecipherable into something so easy a 5 grader could do it

[typicallytina]

This just confused me more catch me failing math ;)

[DonovanEimer]

5 times 17 is 50 plus 35....where did 35 come from???

[asimovianx]

I don't get the where the 24 came from either

[rebexeber]
