Given Inequality:
\( 2 \le 3x - 4 \le 5 \)
Step 1: Add 4 to all parts
\( 6 \le 3x \le 9 \)
Step 2: Divide all parts by 3
\( 2 \le x \le 3 \)
Graphical Representation on Number Line:
Closed circles at 2 and 3,
with the region between 2 and 3 shaded.
Final Answer:
The solution set is
{ x ∣ 2 ≤ x ≤ 3 }
