Exploring Adding and Subtracting Rational Expressions

This video tutorial covers solving one-step equations using inverse operations. It begins with an introduction to the concept of inverse operations, explaining how addition is the inverse of subtraction and multiplication is the inverse of division. The tutorial provides examples of solving equations using these operations, demonstrating how to isolate the variable and check the solution. The video also includes practice problems with solutions, allowing students to apply what they've learned and verify their answers.
