To determine which number from the set {6,7,8, 9} makes the equation 63 ÷ x = 9 true, we can substitute each number into the equation and see which one satisfies it.

1. For x = 6: 63 ÷ 6 = 10.5 ≠ 9
2. For x = 7: 63 ÷ 7 = 9, which is true.
3. For x = 8: 63 ÷ 8 = 7.875 ≠ 9
4. For x = 9: 63 ÷ 9 = 7 ≠ 9

Therefore, the number from the set {6,7,8, 9} that makes the equation 63 ÷ x = 9 true is 7
