Question

Use substitution to determine which number from the set [6,7,8] makes the equation 54÷×=9 true

Answer 1

To solve the equation 54 ÷ x = 9, we can substitute each number from the set [6, 7, 8] for x to see which one makes the equation true.

1. Substitute x = 6:
54 ÷ 6 = 9
9 = 9 (True)

2. Substitute x = 7:
54 ÷ 7 ≈ 7.71
7.71 is not equal to 9, so x = 7 does not make the equation true.

3. Substitute x = 8:
54 ÷ 8 ≈ 6.75
6.75 is not equal to 9, so x = 8 does not make the equation true.

Therefore, the number from the set [6, 7, 8] that makes the equation true is x = 6.
