9w-12

Enter Equation or Inequality


Solve for w in the inequality 9w - 12 ≤ 20

Step 1: Group constants:
We need to group our constants -12 and 20. To do that, we add 12 to both sides
9w - 12 + 12 ≤ 20 + 12

Step 2: Cancel 12 on the left side:
9w ≤ 32

Step 3: Divide each side of the inequality by 9
9w
9
32
9
