Solving Inequalities Using Addition or Subtraction

This lesson, guided by Ms. Huda and Ms. Nisrin, focuses on solving inequalities using addition and subtraction. Students will learn to graph inequalities on a number line and solve various problems, enhancing their algebra skills. Key examples include solving inequalities like -45 > g - 16, 15 ≥ Z + 9, and x + (-14) < 16. After illustration, students will be able to visualize their solutions on a number line, reinforcing their understanding of the concepts taught. Engage with hands-on practice to master the topic!
