Answer:

x ≤ 5

Explanation:

To solve the inequality 3x + 15 ≤ 30, you need to isolate x. Here are the steps:

Start with the original inequality:

3x + 15 ≤ 30

Subtract 15 from both sides of the inequality to isolate the term with x:

3x + 15 - 15 ≤ 30 - 15

Simplify the equation:

3x ≤ 15

Now, to isolate x, divide both sides by 3, as follows:

(3x) / 3 ≤ 15 / 3

Simplify the equation:

x ≤ 5

So, the solution to the inequality is x ≤ 5.
