Introduction to Solving One-Step Equations Using Whole Numbers

Two large seashells lying in the sand on the beach, with the ocean in the background How many seashells did Bobby collect?
During his three-day beach vacation, Bobby is collecting seashells. On the last day of his trip, he picks up 77 seashells and adds them to his bucket. He counts all his seashells and discovers that he has 2323 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.
