• 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.
• 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! :(

• What is a linear expression?\
• "It is made up of two expressions set equal to each other. A linear equation is special because: It has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction."

• how do you do interpreting linear expression?
• i dont get anything tho :(
• You do just do better

• this is really easy all you have to do is watch the videos 3 to 4 times to understand it
• You have to ask the "Why?". In the video the bouquets were made up of four tulips and three violets. The different expressions then changed the different bouquet expressions to be used in a different way, such as `3(4T + 3V)`. In that case it took the equation for the bouquet `4T + 3V` and multiplied it by three for three bouquets. You need to think the "Why?" Doing that will show you the meaning, like "Why did they multiply it by 3?" and that's because they wanted three bouquets, which gives you the answer. Hope that helps! ^_^
