Use substitution to determine which number from the set {6, 7, 8} makes the equation 54÷x=9 true.(
Substitute each number from the set {6, 7, 8} into the equation 54÷x=9.
1. If x = 6: 54 ÷ 6 = 9
Simplifying the left side, 54 ÷ 6 = 9
So, x = 6 satisfies the equation.
2. If x = 7: 54 ÷ 7 ≠ 9
The result is not 9, so x = 7 does not satisfy the equation.
3. If x = 8: 54 ÷ 8 ≠ 9
The result is not 9, so x = 8 does not satisfy the equation.
Therefore, the number from the set {6, 7, 8} that makes the equation 54 ÷ x = 9 true is x = 6.
