Overview
On this page, we review methods to solve linear equations.
Basic Learning Objectives
These are the tasks you should be able to perform with reasonable fluency when you arrive at your next class meeting. Important new vocabulary words are indicated in italics.
- Use basic algebra to solve a linear equation involving only one variable.
Advanced Learning Objectives
In addition to mastering the basic objectives, here are the tasks you should be able to perform after class, with practice:
- Solve a linear equation involving more than one variable, by “isolating” one variable, i.e. expressing it as a formula in terms of the others.
To prepare for class
