Question

Solve and graph the solution set of:

3x – 2 > 19 or 3 – 2x ≥ – 7, x ∈ R

Answer 1

3x – 2 > 19 or 3 – 2x ≥ – 7

3x > 21 or – 2x ≥ – 10

x > 7 or x ≤ 5

Graph of solution set of x > 7 or x ≤ 5 = Graph of points which belong to x > 7 or x ≤ 5 or both.

Thus, the graph of the solution set is
