Lailah Fitzpatrick · 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.

Vazquez · Answer 2

Answer:the expression - 3 + 2x is equivalent to 2x - 3. I know it is equivalent because for every value of x that is substituted in, the two expressions simplify to the same value. I took the expression and used the commutative property to not change the value.
