Dec 18, 2007 · Solve 3 – (2x + 5) = 5 + x + 2(4x – 6) Solving Inequalities – Messier Ones. It’s the exact same thing we’ve been doing, except our = sign looks like , ≤, ≥ All you need to do is remember the stuff we’ve already learned about inequalities: Use the same steps as with solving equations, the only difference is the inequality symbol!

THE ONE DIFFERENCE BETWEEN SOVING EQUATIONS AND INEQUALITIES. When you multiply or divide on both sides by a negative number, you must turn the inequality around. 8 – 3x < 17 -8 -8 - 3x < 9-3 -3 * Dividing both sides by -3, you must turn the inequality around. It changes from < to >. x > -3. Solve and Graph:
