Solving One-Step Inequalities Using Addition and Subtraction
Solving One-Step Inequalities Using Addition and Subtraction is a Grade 7 math skill from Big Ideas Math, Course 2, covering Inequalities. To solve an inequality using addition or subtraction: 1. We can add the same quantity to both sides of an inequality. Explanation Solving inequalities using addition or subtraction works exactly like solving equations - you perform the same operation on both sides to isolate the variable. The key advantage of addition and subtraction is that the inequality sign never changes direction, making these operations straightforward and reliable for solving inequalities.
Key Concepts
