The video tutorial by Mr. J covers solving one-step inequalities using addition and subtraction. It explains the process of isolating the variable by applying inverse operations and maintaining balance on both sides of the inequality. The tutorial highlights the difference between equations and inequalities, emphasizing that inequalities have infinite solutions. Through four examples, Mr. J demonstrates how to solve inequalities and verify solutions by substituting values. The video concludes with a summary of the steps involved in solving one-step inequalities.

What is the main difference between solving equations and inequalities?

• Equations have multiple solutions, while inequalities have one solution.

• Equations have one solution, while inequalities have multiple solutions.

• Equations and inequalities both have one solution.

• Equations and inequalities both have multiple solutions.
