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.
