Answer:

D) 3x - 2x = 10

Step-by-step explanation:

To combine like terms, you add or subtract terms that have the same variables and exponents. In the problem we are given, 3x and 5x are like terms; we would add them together and then continue solving.

In choice A, there are no like terms to combine.

In choice B, we would use the distributive property; after that, there are no like terms to combine.

In choice C, we would cancel the 4; there are no like terms to combine.

Choice D has two like terms, 3x and 2x. We would subtract them and then continue solving.
