To determine which number(s) from the set {9, 12, 14} make the equation 6x=72 true, we can substitute each number into the equation and see if it satisfies the equation.
1) Substituting 9 into the equation:
6 * 9 = 54 (not equal to 72)
2) Substituting 12 into the equation:
6 * 12 = 72 (equal to 72)
3) Substituting 14 into the equation:
6 * 14 = 84 (not equal to 72)
Therefore, the number 12 from the set {9, 12, 14} makes the equation 6x=72 true.
