Answer:
To solve the inequality 3x + 15 ≤ 30, we can follow these steps:
1. Subtract 15 from both sides of the inequality: 3x + 15-15 ≤ 30 - 15 3x ≤ 15
2. Divide both sides of the inequality by 3 to isolate the variable x: (3x)/3 ≤ 15/3 X≤5
Therefore, the solution to the inequality 3x + 15 ≤ 30 is x ≤ 5. This means that any value of x that is less than or equal to 5 will make the inequality true. For example, x = 0, x = 3, or x = 5 are all valid solutions.
