Answer: Reflexive Property
Step-by-step explanation:
The reflexive property means any term is equal to the same term or any value is the same anywhere. Since 3x and 3x are both the same, its reflexive property. This isn't to get confused with symmetric property, if two terms are equal to each other, they will still be equal to each other if the equation is flipped.
3x=3x is reflexible
2·3x=6x is symetric
Hope that helped a lot. Let me know any further questions.
