What is the value of 7x − 11 when x = 3?

16
20
-9
-5

The correct answer is: 16

In order to find the value of 7x - 11 when x = 3, we need to substitute 3 in for x. So, we have 7(3) - 11, which simplifies to 21 - 11 = 10. However, option B, 20, and option D, -5, are incorrect because they do not follow the order of operations. Option C, -9, is incorrect because it is not consistent with the given equation. Therefore, the correct answer is A, 10.
