Khan Academy: "Two-Step Equations"

Watch these videos and take notes. Now that you are familiar with basic equations, the first video introduces an equation that requires more than one step to solve. Note that x is found by performing the operations in the inverse order: first subtraction and then division. The second video contains a very detailed explanation of how to solve two more equations of the form ax + b = c. The third video contains fractions, but it still can be solved as any other equation of the form ax + b = c.
