To find out which of the numbers 6, 7, and 8 is a solution of 3x ≤ 18, we can substitute each number into the inequality and check if the equation holds true.
For 6:
3(6) ≤ 18
18 ≤ 18
This equation is true.
For 7:
3(7) ≤ 18
21 ≤ 18
This equation is false.
For 8:
3(8) ≤ 18
24 ≤ 18
This equation is also false.
Therefore, the number 6 is the only solution of 3x ≤ 18.
