Final answer:
To solve the inequality X-6 ≤ 3, add 6 to both sides of the inequality to get X by itself. The solution is X ≤ 9.
Step-by-step explanation:
The question is asking to solve the inequality X-6 ≤ 3. To do this, we need to isolate X on one side of the inequality. We can add 6 to both sides of the inequality to get X by itself.
X-6 + 6 ≤ 3 + 6
X ≤ 9
Therefore, the solution to the inequality is X ≤ 9. This means that any value of X that is less than or equal to 9 satisfies the inequality. For example, X = 5 is a valid solution.
