Equations and Inequalities Mastery Review

Miss Stig reviews solving equations and inequalities, emphasizing isolating variables using inverse operations. She explains the process with examples, highlighting the importance of checking solutions. The video covers special rules for inequalities, such as flipping the inequality symbol when multiplying or dividing by a negative number. Graphing solutions on a number line is discussed, along with vocabulary for inequality symbols. The video concludes with examples of writing equations and inequalities, encouraging students to ask questions if needed.
