In Lesson 21, students will learn to solve one-step equations using multiplication and division. The lesson includes examples that guide learners through the process of evaluating equations. For instance, if Anita, an architect, designs a rectangular room with an area of 126 square feet and a length of 12 feet, students will calculate the room's width using the equation. Homework assignments will reinforce these concepts, helping students practice and master one-step equations.
