2b - 4 ≥ 2 ; [1,2,3,4]
Plug in each number for "b" in the inequality
2(1) - 4 ≥ 2
2 - 4 ≥ 2
-2 ≥ 2
1 is not a solution because -2 is not greater than or equal to 2.
2(2) - 4 ≥ 2
4 - 4 ≥ 2
0 ≥ 2
2 is not a solution because 0 is not greater than or equal to 2.
2(3) - 4 ≥ 2
6 - 4 ≥ 2
2 ≥ 2
3 is a solution because 2 is equal to 2.
2(4) - 4 ≥ 2
8 - 4 ≥ 2
4 ≥ 2
4 is a solution because 4 is greater than 2.
