In this lesson, Julie Harland shows how to determine if a number is a solution to a given equation. An equation has an equal sign and the expressions on either side must be equal to each other. If a number is plugged in for the variable in the equation and the left and right sides are equal, then it is a solution. The lesson covers six problems, including equations with variables and fractions. Additionally, students learn how to rewrite equations to simplify the process of plugging in numbers for variables.
