Question

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?

Answer 1

It's the third step that's incorrect.\[x+(5y-y)\]\[x+(5-1)y\]using the distributive property of addition.
