If X is 5, then 6X is equal to 30. You can see to be able to get 30, you have to multiply 6 to X, which in this case is 5. So 6 times 5, you will now get the answer which is 30. In cases that X have other values, you just have to multiply it with 6 to get the answer. This problem can not have 30x or 5x as the results. As the value of X is already given, then, you will get the answer specifically.
