Answer:
the answer is 2x-3 = 9
Step-by-step explanation:
the question is telling us to look for the expression that is equal to both sides of =. count the blocks on the right side which is 9. count the ones on the left which is 2x and 3. find x which is 6. this allows to solve both of the possible answers (this case being 2x - 3 or 2x + 3)
2x6 + 3 = 15
2x6 - 3 = 9
^ this expression equals 9 so that is your answer. hope that made sense
