You can put this solution on YOUR website!
I don't have your book, but a lot of times that means to state the property you used for each step.
There are associative properties, inverse properties, commutative properties, distributive properties, that kind of thing.
Remember, I'm taking an educated guess because I don't have your book.
Happy Calculating!!!
