A student solved the inequality  as follows: Step 1: 1 – 4x ≤ 25 Step 2: -4x ≤ 24 Step 3: x ≤ -6 Student’s Graph: Solid circle at -6 with arrow pointing to the left. Task: What was the student’s mistake in  Step 3. Explain the rule that was violated, state the correct solution, and describe the corrected graph.

 Solve the multi-step inequality and select the correct solution set: -4(x + 3) – 2 > 14
