Evaluate the following student's solution to 3x − 4 = 11: they added 4 to both sides to get 3x = 7, then divided by 3 and concluded x = 7/3. Determine whether the steps and final answer are correct, and if not provide the correct solution.

• A. Partially correct: The student should have subtracted first, then multiplied. This would give x = −7/3 and correct the sign error.
• B. Partially correct: The student should have added 3 instead of 4 to both sides, leading to 3x = 14 and x = 14/3, which is the correct adjustment.
• C. Incorrect: The student added 11 and 4 incorrectly. The correct solution is x = 5: after getting 3x = 15, divide both sides by 3.
• D. Correct: 3x = 7 and x = 7/3 is the right sequence because adding 4 to 11 yields 7 during simplification.

Answer: (C)
