Lesson Summary:
In this lesson, students are taught how to write algebraic expressions from word problems, as well as how to solve and check algebraic equations with variables on both sides. The instructor breaks down how to find the sum of four consecutive odd integers as an algebraic expression in x, and simplifies the expression for better understanding. Additionally, the lesson provides examples of how to solve equations step by step and check the solutions to avoid errors.
Lesson Description:
Writing algebraic expressions from word problems, and solving and checking algebraic equations with variables on both sides.

Staff Review
This video tackles a topic that is often very difficult for students -- writing algebraic expressions from a word problem. Equations with variables on both sides are also solved in this video. Everything is explained very well.
