Isolate z in the inequality: Step 1: Start by isolating z in the inequality.3 < 9 - z Subtract 9 from both sides to isolate the term with z.3 - 9 < -z-6 < -z
Multiply by −1 to solve: Step 2: Multiply both sides by −1 to solve for z. Remember to flip the inequality sign because we are multiplying by a negative number.-1(-6) > -1(-z)6 > z
