Solve Two-Step Equations Using a Number Line

The video tutorial explains how to solve equations by isolating variables using inverse operations. It covers the importance of the equal sign in equations and demonstrates solving equations with variables through examples. The tutorial emphasizes the use of inverse operations, such as addition and subtraction or multiplication and division, to isolate variables. It provides step-by-step solutions for equations involving variables x and t, and highlights the necessity of performing operations on both sides of the equation. The video concludes by encouraging practice with these methods.

What is the primary purpose of an equal sign in an equation?

• To denote the end of a mathematical operation

• To indicate the start of an equation
