The solution involves substituting each number into the inequality and checking if it is true or false.
1. Substitute x = 0:
5(0) + 2 ≥ 12
0 + 2 ≥ 12
2 ≥ 12
This is false, so 0 is not a solution.
2. Substitute x = 1:
5(1) + 2 ≥ 12
5 + 2 ≥ 12
7 ≥ 12
This is false, so 1 is not a solution.
3. Substitute x = 2:
5(2) + 2 ≥ 12
10 + 2 ≥ 12
12 ≥ 12
This is true, so 2 is a solution.
Therefore, the only number that is a solution of the inequality is 2.
