We can first find the value of x by solving the eqaution:
6 ≥ x/3 - 3
6+3 ≥ x/3
9 ≥ x/3
9×3 ≥ x
27 ≥ x
As we change the unknown to left hand side, the symbol will need to change as well:
x ≤ 27
As x is smaller or equal to 3, the options that are correct are:
21, 27, 24
As the answer 30 and 33 are larger than 27, they are incorrect.
Therefore, the answers are: 21, 27, 24.
Hope it helps!
