Two Step Equations

Two Step Equations

By the end of the lesson, you will be able to solve a two step equation using inverse operations.

​Solving Two Step Equations

• ​Get out a piece of paper to complete the examples from the video.

• ​When you get to the question where you're prompted to pause, make sure to complete those on. your own and check your work with your neighbors and Mrs. Jackson.

Multiple Choice
