Solving Two-Step Equations: A Comprehensive Review

The video tutorial introduces a series called 'Back to Basics' focusing on solving two-step equations. The instructor explains the process of isolating variables by removing terms that are 'floating around' and those that are 'attached' to the variable. The tutorial covers examples involving division, subtraction, multiplication, and addition, demonstrating how to solve for the variable step-by-step. The instructor emphasizes the importance of understanding each step and encourages viewers to rewatch the video for better comprehension.
