Equations for beginners

4 videos
2 skills
Like previous tutorials in this topic, we'll introduce you to the most fundamental ideas of what equations mean and how to solve them. We'll then do a bunch of examples to make sure you're comfortable with things like 3x – 7 = 8. So relax, grab a cup of hot chocolate, and be on your way to becoming an algebra rockstar. And, by the way, in any of the "example" videos, try to solve the problem on your own before seeing how Sal does it. It makes the learning better! Common Core Standard: 6.EE.B.7

Simple equations of the form ax = b
