Inequalities

The video tutorial introduces inequalities, explaining their symbols and how they compare quantities. It demonstrates solving inequalities through examples, such as f + 3 < 9 and x + 5 > 12, by substituting variables with possible values to find solutions. The tutorial also covers solving x + 5 ≤ 8, emphasizing isolating the variable and performing operations on both sides of the inequality. The video concludes with encouragement for students to continue practicing inequalities.
