Solving Inequalities: Adding and Subtracting Techniques

The video tutorial explains how to solve inequalities by adding and subtracting, similar to solving equations. It provides examples, such as solving n + 6 > 3 and P - 7 ≤ -3, and emphasizes checking solutions. Additionally, it includes a practical example involving sales targets to illustrate the application of inequalities in real-life scenarios.

What is the first step in solving the inequality 'n + 6 > 3'?

• Multiply both sides by 6

• Divide both sides by 6

• Subtract 6 from both sides

• Add 6 to both sides
