How to Solve One-Step Inequalities (with Negatives!)

Ready to master one-step inequalities? The most important rule is to remember when to flip the inequality sign! In this video, we'll explore why multiplying or dividing by a negative number flips the inequality. Then we'll walk through several clear examples, including graphing the solutions on a number line. Stop making this common mistake and start acing inequalities! Treat the #inequality symbol like an equal sign and "undo" the operations than are being done to the variable to both sides. Subtraction and Addition undo each other, and Multiplication and Division undo each other. Remember, if you multiply or divide by a negative, then you need to switch the direction of the inequality. This video could work for #Algebra students who were absent, or in a flipped classroom.
