NEED HELP ASAP PLEASE HELP!

What word phrase represents the expressions
-2 + 3x and 3x + (-2)?

Are the two expressions equivalent? Please explain!

Answer 1

Both expressions are equivalent.

To prove that, let x equal a random number. For example, let x=1.
-2+3x and 3x+(-2)
-2+ (3 X 1)= 1.
(3 X 1) + (-2) =1

Answer 2

These two expressions are equivalent because if you had an equal sigh and equal it to the same answer like 3x+(-2)=2.

Anyways this is called the communative property. The comunuty property is when you change the statement of the equation or the expression.

Im sorry, explaining this is really weird. Trust me this is easier then it sounds. I hope this helps you.
