Cason Meyer · Answer 1

Two expressions that would be equivalent are 2x + - 3 and - 3 + 2x

Step-by-step explanation:

To find these, use two basic properties of addition.

The first that I used was that there is that adding a negative is the same as subtracting.

The second that I used is the fact that you can change the order in addition and it does not change the answer.
