Use substitution to determine which number from the set 6,7,8 makes the equation 54 divide by x=9 true
To find which number from the set 6, 7, or 8 makes the equation 54 divided by x equal to 9 true, we can substitute each number into the equation and see which one results in the equation being equal to 9.
1. Substitute x = 6:
54 ÷ 6 = 9
9 = 9
2. Substitute x = 7:
54 ÷ 7 ≠ 9
The equation is not equal to 9 when x = 7.
3. Substitute x = 8:
54 ÷ 8 ≠ 9
The equation is not equal to 9 when x = 8.
Therefore, the number from the set 6, 7, or 8 that makes the equation 54 divided by x equal to 9 true is x = 6.
