Solving One-Step Equations with Negatives

The video tutorial by Mr. J covers solving one-step addition and subtraction equations involving negative numbers. It explains the concept of isolating the variable using inverse operations, ensuring balance by performing the same operation on both sides of the equation. The tutorial provides examples for both addition and subtraction equations, demonstrating how to solve them step-by-step. It emphasizes the importance of checking solutions by substituting them back into the original equations. The video concludes with a summary of the methods discussed.
