Notes Review

Rules for Solving Inequalities Notes 1. Solve just like you would an equation. - THERE IS ONLY ONE EXCEPTION: If you multiply or divide by a negative number you MUST reverse the inequality symbol.

Notes Ex. Solve the inequality. Do we have to flip the sign? Isolate the variable! Ex. Do we have to flip the sign? Isolate the variable! Now you try.
