Solving Equations Using the Distributive Property

Mrs. Angel introduces solving equations using the distributive property with positive numbers. The lesson covers simplifying expressions and solving equations using two methods: applying the distributive property first and using properties of equality only. Students are encouraged to practice both methods and choose their preferred approach. The lesson concludes with a practice exercise and a summary of key points.

What is the main focus of this lesson?

• Graphing linear equations

• Combining like terms

• Using the distributive property with positive numbers

• Solving quadratic equations
