3x + 2 = 3x + 2 pls help me I do not understand

3x+2=3x+2 because, you have to combine your like terms, so here is an example..

                 3x + 2

there are no like terms to combine here so the problem stays how it was, so there saying 3x+2 = 3x+2 because they're stating the problem then saying that the answer is the same because there is no like terms her to combine.

Hope this helps,

the answer is "add 2y and y"

step-by-step explanation:

you need to collect the like terms first.
