• This video is so confusing that I feel brain dead like Kaminari...somone explain this more simple to me so I don't fry my brain with electric from my headphones because they are dead...
• Thanks for advice. And at least someone understood my joke...I'm just trying to lighten up the mood with comedy from My Hero Academia..And I was trying to be funny, I like making jokes like that.
• why don't the videos match what the questions are talking about in the actual practice lesson?
• This video uses the actual practice lesson. The format looks different because it is the old format that KA had until a couple of years ago. But the problems do come from the exercise set.
• this isnt helping at all
• Well, it makes sense. Variables also have several unknowns. But it's one of each. 2V + V
V in this case is equal to 1. So the solution is 3V.
And remember the video before. The variable means 1V. V can be anything.
• Can someone explain this, please?

• why are the problems set up differently?
• Because the website was updated, and the problems were set up in a different way. When Sal made the video, the exercise was set up the way it was in the video.
• watched this and the pony video about a hundred times and i still dont understand it! this is my last skill before im done with 7th grade math and im so confused! :(
