Introduction to Solving One-Step Equations Using Whole Numbers
During his three-day beach vacation, Bobby is collecting seashells. On the last day of his trip, he picks up [latex]7[/latex] seashells and adds them to his bucket. He counts all his seashells and discovers that he has [latex]23[/latex] in all. Knowing this, how can Bobby determine how many shells he picked up over the first two days of his trip? One way he can figure it out is to write an equation. Read on to learn about properties of equations and develop your skills when solving equations.Learning Outcomes
