Answer:
x ≤ 3
Explanation:
To solve the inequality 5x ≤ 15, we need to isolate x on one side of the inequality. We can do this by dividing both sides of the inequality by 5:
5x/5 ≤ 15/5
x ≤ 3
So the solution to the inequality is x ≤ 3. This means that any value of x that is less than or equal to 3 will make the inequality true. To graph this inequality on a number line, we draw a closed circle at point 3 and shade the area to the left of the circle to represent all the possible values of x that satisfy the inequality:

3
The circle is closed to indicate that x can be equal to 3, and the shading indicates all the values of x that are less than or equal to 3.
