Hi @HappyHolloween ! Welcome To Openstudy. :)

Yes, I can help.

Okay, so notice that -18xy has two different variables: x and y. In order for another term to be like terms, it must also include both x and y.

Does that help?

kinda
OpenStudy (studygurl14):
For example, 2y and 4y are like terms because they both have the y variable. 3x and 5x are like terms because they both have the x variable. 2xz and 5xz are also like terms because they share both the x and z variables.

Does that clarify?
