Use substitution to determine which number(s) from the set {9, 12, 14} make the equation 6x=72 true.(1 point)
x = ?
To solve the equation 6x = 72 using substitution, we need to substitute the given numbers from the set {9,12,14} into the equation and see if it holds true.
1. Substituting x = 9:
6(9) = 54, which is not equal to 72.
2. Substituting x = 12:
6(12) = 72, which is equal to 72.
3. Substituting x = 14:
6(14) = 84, which is not equal to 72.
Therefore, the only number from the set {9, 12, 14} that makes the equation 6x = 72 true is x = 12.
