Step 1. You can think of the above inequality consist of two inequalities. That is,
and
Step 2. Then, on the number line we have
Step 3. Now, the graph is going from the red dot at 2/3 to the right pass the green dot to positive infinity or a positive large number.
Step 4. The graph is going from the green dot at 5/2 to left pass the red dot to minus infinity or a negative large number.
Step 5. ANSWER. Finally, combining these two graphs as described above in Steps 3 and 4 will overlap with each other. The overlap and solution is between 2/3 and 5/2 or between the red and green dots as shown in the graph.
I hope the above steps were helpful.
