This topic is in the 'Equations and Functions' section. Equations are like mini-puzzles where you have to figure out what set of math steps you can take in order to get one of the variables by itself. Sometimes you can solve the puzzle in just one step, with one simple mathematical operation. Other times you'll need two steps to get the job done. We've got a lot of great examples tutorials to help you see the variety of techniques that are out there to solve equations. Just remember to focus on the variable that you are trying to solve for, and make sure that you apply any math steps that you take to both sides of the equation!
