To solve x − 8 = 17, add  \n8 to both sides.  \n2.) 2. ) Correct: n = 37 (64−27=37) | Mistake: Arithmetic error: 64 − 27 = 37, not 47. The inverse operation was correct.  \n3.) 3. ) Correct: x = 40 (8×5=40) | Mistake: Divided instead of multiplying. To solve x ÷ 5 = 8, multiply both sides by 5.  \n4.) 4. ) Correct: y = 12 (84÷7=12) | Mistake: Arithmetic error: 84 ÷ 7 = 12, not 14. Check the division carefully.  \n5.) 5. ) Correct: m = 33 (52−19=33) | Mistake: Did not subtract 19 from the right side.

To solve 9a = 72, divide both sides by 9.  \n7.) 7. ) Correct: n ≥ 8 (13−5=8) | Mistake: The student dropped the inequality symbol and wrote = instead of ≥ . Must write n ≥ 8.  \n8.) 8. ) Correct: x > 19 (30−11=19) | Mistake: Added 11 instead of subtracting. To solve x + 11 > 30, subtract 11 from both sides.  \n9.) 9. ) Correct: n \u003C 9 (27÷3=9) | Mistake: Subtracted 3 from 27 instead of dividing.
