To find the number in question, we start with the information given: if 9 is subtracted from an unknown number, the result is 5. We can express this mathematically as follows:

Let the unknown number be represented by ( x ). The equation can be formulated as:

[ x - 9 = 5 ]

To solve for ( x ), we need to isolate it on one side of the equation. We can do this by adding 9 to both sides:

[ x - 9 + 9 = 5 + 9 ]

This simplifies to:

[ x = 14 ]

Thus, the number we are looking for is 14. This makes the correct answer accurate, as the process allows us to explicitly calculate the value satisfying the condition presented in the question.

In these types of problems, it's essential to set up an equation based on the scenario described and then manipulate it algebraically until the variable of interest is isolated.
