Compound Inequalities Tips | Easy Trick for Solving “AND” Inequalities

In this video, we’ll walk through how to solve compound inequalities (AND style) with a simple math trick that works every time. Whether you’re just starting Algebra 1 or reviewing, this example-packed video shows you how to split up the inequality or solve it “as is,” graph the solution, and even write inequalities from a graph. If compound inequalities have ever been confusing, this video breaks it down in a clear, step-by-step way with real-world examples (like spending between $20 and $50 in a store). 📌 You’ll learn how to: Solve AND compound inequalities two different ways Graph inequalities on a number line (open vs closed circles) Avoid common mistakes with inequality signs Write inequalities from a graph Use a quick math hack to check your answers How to #solve "and" style compound inequalities. Since there are two #inequality symbols with the variable in the middle, treat it like an equation with 3 "sides" and "undo" the operations than are being done to the variable to all three sides. Subtraction and Addition undo each other, and Multiplication and Division undo each other. For graphing, you'll put dots on both numbers and shade between. When writing these inequalities, the common mistake is having the inequalities facing the wrong way. Both inequalities should be less than's. This video could work for #Algebra students who were absent, or in a flipped classroom.
