Exploring Adding and Subtracting Rational Expressions

This video tutorial covers solving one-step equations using multiplication and division. It explains the four-step process: locating the variable, identifying the operation, using inverse operations, and checking the solution. The tutorial provides examples for both multiplication and division, emphasizing the importance of verifying solutions. A mixed review section allows for practice, and the video concludes with a focus on the necessity of checking solutions to ensure accuracy.

What is the first step in solving one-step equations?

• Use inverse operations

• Locate the variable

• Find the operation tied to the variable
