Solving Equations with Like Terms

The video tutorial covers solving equations with like terms, starting with a review of basic equation-solving steps. It introduces the concept of combining like terms and provides multiple examples, including equations with fraction and decimal coefficients. The tutorial also includes real-world applications, such as calculating the perimeter of a rectangle and solving cost-related problems. Each example is broken down step-by-step to demonstrate the process of simplifying expressions and solving equations.

What is the first step in solving an equation with like terms?

• Add or subtract to remove the constant

• Multiply or divide to remove the coefficient

• Combine like terms on the same side of the equal sign

• Move terms to the other side of the equal sign
