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
