Answer (3)

12 - 3 = 9 or 12 - 9 = 3
they both use the same numbers. subtraction is the opposite of addition and allows us to check our answers

One possible answer is:
12 - 3 = 9.
Explanation :
The two facts are related in that they are opposite statements. Addition and subtraction are opposite operations; subtraction will undo addition, and addition will undo subtraction.
In 3+9 = 12 and 12-9 = 3, we have basically "undone" the addition from the first statement in the second statement.

A related subtraction fact for 9 + 3 = 12 is 12 − 3 = 9 . These facts are related because addition and subtraction are inverse operations of each other. Thus, one operation can reverse the other to return to the original numbers.
