Respuesta :
Well it's only B and D because like terms are where the variables are the same. This only happens at B and D because B has only jk's, and D only has x's
Answer:
Sets B and D
Step-by-step explanation:
Set B contains only like terms; every term given ends in the letters jk.
Set D contains only like terms (provided that you meant (1/3)x and not 1/(3x) ).
