    Which step was incorrect, and what should be the correct step that Ann should use? Step 2 was incorrect. Correct step: −2x − (y − 3y); using associative property of addition Step 1 was incorrect. Correct step: 2x + y − 3y; using commutative property of addition Step 1 was incorrect. Correct step: 2x +3y − y; using commutative property of addition Step 2 was incorrect. Correct step: −2x + (y − 3y); using associative property of addition
