Solving Two Step Equations in Algebra 1

This lesson covers solving two-step equations using inverse operations. It explains how addition is the inverse of subtraction and vice versa, and how multiplication is the inverse of division. The lesson introduces the concept of reverse order of operations, using examples to demonstrate solving equations step-by-step. It also covers handling complex fractions and checking solutions.
