Nine less than the product of a number and 4 is at most 11

Answer-

I don't know what you want me to do with that, but I'll give you the equation and the answer of it:

Equation: 11 ≥ (4*n) - 9

Answer: n could be five and below. For example, 5, 4, 3, 2, and 1 could work

Explanation-

If you take one of the numbers I used in the example and plugged it in, it would kinda look like this:

11 ≥ (4*4) - 9

4*4=16

16-9=7

Since it said at most 11, this would be reasonable because 11 ≥ 7.
