If 3x + 1 ≤ 16 and x ∈ {real numbers}, then the values of x represented on a number line are:

1.

2.

3.

4.

If 3 - 2x ≥ x - 10, x ∈ W, the solution set is:

1. {1, 2, 3, 4, ……………}

2. {1, 2, 3, 4, 5}

3. {o, 1, 2, 3, 4}

4. {1, 2, 3, 4}

If x is an integer and -2(x + 3) > 5; the solution set on the number line is:

1.

2.
