Answer:

subtraction property of equality

Explanation:

Some others also asked this question on brainly and they said that is was the subtraction property of equality BUT the person who was asking the question included the answer choices. So just so you know, if not for people who know what the options are, it would be a whole lot harder to answer the question just a heads up.
