1 answer

Let's replace x with each number from the set {6, 7, 8} in the equation 54/x = 9:

1. If x = 6:
54/6 = 9
9 = 9
This is a true statement.

2. If x = 7:
54/7 ≠ 9
7.71 ≠ 9
This is not a true statement.

3. If x = 8:
54/8 ≠ 9
6.75 ≠ 9
This is not a true statement.

Therefore, the number from the set {6, 7, 8} that makes the equation true is x = 6.
