Question

8.
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

Which step was incorrect, and what should be the correct step that Dom should use? (6 points)

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
Step 3 was
