@EXOEXOEXO what do u mean?

OpenStudy (exoexoexo):

for example: 2n and n are likely terms because they have the same variables

OpenStudy (anonymous):

OpenStudy (exoexoexo):

in the expression 4n + 9 + n + 5n you can combine the terms with the same variables by adding them up

OpenStudy (anonymous):

18n
