x -9 ≤ 18 -2x

+2x +2x

3x -9 ≤ 18

+9 +9

3x ≤ 27


(3x)/(3)
(27)/(3)

Answer:

x ≤ 9

Explanation:

Step 1: Write inequality

x - 9 ≤ 2(9 - x)

Step 2: Solve for x

  1. Distribute 2: x - 9 ≤ 18 - 2x
  2. Add 2x on both sides: 3x - 9 ≤ 18
  3. Add 9 to both sides: 3x ≤ 27
  4. Divide both sides by 3: x ≤ 9

Here we see that any solution less than or equal to 9 would work.
