Solving for a Variable

Missed the previous lesson?

Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

this Kinda helped me in some of the questions, and I need more examples on this too , but the part the mostly helped me, is that i need to divide, and you reminded me of that, thanks. :)

Thank you so much!  I'm having a really hard time in my Algebra class because I don't really have a good teacher, but now I think I've got the hang of this concept!

[noodle]

Start of the lesson: I am utterly confused and have no idea what I'm doing
End of the lesson: I understand it completely; it's just like a two step equation with more variables. Thanks dude :)
