Answer:
As per the statement:
We have an inequality:

Divide both sides by 15 we get;

or

The solution set for this inequality is:

Take any three values of x to make the given inequality.
Put x = 1

True.
Put x = 2

True.
Put x = 3

True.
Therefore, the values of x that would make this inequality
true are:
x = 1, 2 and 3
