One Step Equations Challenge

The video tutorial covers solving one-step equations by isolating the variable. It begins with defining variables and explaining their role in equations. The tutorial then provides four examples, each demonstrating a different operation: addition, subtraction, multiplication, and division. For each example, the instructor explains how to perform the inverse operation to isolate the variable and solve the equation.

What does a variable represent in mathematics?

• A known constant

• A type of function

• An unknown number

• A specific formula
