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 check if it satisfies the equation.
1. Substitute 6:
63 ÷ 6 = 10.5 (not equal to 9)
2. Substitute 7:
63 ÷ 7 = 9 (equals to 9)
3. Substitute 8:
63 ÷ 8 = 7.875 (not equal to 9)
4. Substitute 9:
63 ÷ 9 = 7 (not equal to 9)
Therefore, the number 7 from the set {6, 7, 8, 9} makes the equation 63 ÷ x = 9 true.
Use substitution to determine which number from the set \{6, 7, 8, 9\} makes the equation 63 ÷ x = 9 true.
