The equation 18 + 2x ≥ 36 can be simplified by subtracting 18 from both sides:

2x ≥ 18

Now, let's solve for x:

x ≥ 9

In other words, x must be greater than or equal to 9.

Looking at the given sets of numbers:

1) In the set 9, 10, 11, 12, all the numbers are greater than or equal to 9. Therefore, all the numbers in this set are solutions to the equation.

2) In the set 9, 8, 7, 6, only 9 is greater than or equal to 9. Therefore, only one number in this set is a solution to the equation.

3) In the set 0, 3, 9, 12, only 9 and 12 are greater than or equal to 9. Therefore, two numbers in this set are solutions to the equation.

4) In the set 8, 7, 6, none of the numbers are greater than or equal to 9. Therefore, none of the numbers in this set are solutions to the equation.

Therefore, the sets in which all the numbers are solutions of 18 + 2x ≥ 36 are:

- 9, 10, 11, 12

- 0, 3, 9, 12
