Dom wrote the following steps to simplify the expression (x − y + 5y).
Step 1: x + 5y − y; using commutative property of addition
Step 2: x + (5y − y); using associative property of addition
Step 3: x − (5 + 1)y; using distributive property of addition
Step 4: x − (6)y; simplifying

Best ResponseYou've already chosen the best response.1Which step was incorrect, and what should be the correct step that Dom should use? Step 3 was incorrect. Correct step: x + (5 − 1)y; using distributive property of addition Step 2 was incorrect. Correct step: x − (5y − y); using associative property of addition Step 2 was incorrect. Correct step: x + (5y + y); using associative property of addition Step 3 was incorrect. Correct step: x − (−5 − 1)y; using distributive property of addition
