Multi-Step Equations

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.

I always wonder what program he uses to draw on it seems awesome for tutorials please tell me someone?

[Jitnaught]

6:50 the more times you listen to this the weirder it sounds

[Rayman]

keep it up sal... you've produced 1328 ways to help people acedemically...shoot for 2000 and beyond!

Without you i would fail my class then fail geometry and then algebra 2 and then pre calc and then calc and then trig and then i wouldnt be succesful and get a good job and then i would be poor and eventually die of hunger. You are appreciated

[sandman]

thx i have an exam tomorrow and this just helped

[nayvemcay]

these videos always help me with my homework thank you so much

[gabriellelyse]

This was very helpful, Sir! Thank you!

[w.a.]

This for my extra credit so thx Khan Academy

[valromo]

Thanks man, I know these videos will help out a lot when I take my practice staar tomorrow :)

[hmoodythebest]

Your helpfull complete that as i am a math teacher i will till all my students to wathc your videos better than minecraft and fifa these are ther life thx copleye dat

[LegoStarWarsFilms]

the first one is -22.5 if you divide -135 by 6

[momtobrndon]

Can you do a video that doesn't have fraction answers? We're not doing that yet.

[Dory_Swim]

The first problems dose it equal 22.5

[junaidharris]

But the question is wrong because in algebra there always be a question of finding "w" in that sort of question !
i probally disagree with the answer of equally proving LHS=RHS

[junaidharris]

Easy step :- 7(w+20)-w=5
7w+140-w =5
6w+140=5
6w=5-140
w=135/6
w = 22.5
hhmm what do u think?
Easy or hard?

[erinn]

It is a rare video where you see 0 dislikes. :3

[jonathancalderon]

what the fuck the first one is -22.5

[onesandzeroes]

The word problem was a bit irritating because the result was nonsensical in the context, so I thought I was doing sth wrong when tackling it on my own. Sal got the same result but didn't seem to be bothered. I wish somebody thought some of these problems through when making them instead of pulling them out of their asses 🎃

[lwitz]

Yea pup. Sorry but we want help. Not gaming...

[Hendrixhimself]

You can simplify -135/6 further, to -45/2
