Answer:
Explanation:
The transitive property of equality says--in very informal terms--if thing 1 = thing 2 and thing 2 = thing 3, then thing 1 = thing 3. See how thing 2 appears twice? That's a "spoiler alert" for this question.
So, what are thing 1, thing 2, and thing 3?
Take a look at how the answer space begins: 9y. That must be thing 1 because the conclusion of the transitive property is thing 1 = ...
Now, what is mentioned twice? 2x. That must be thing 2.
The remaining expression is thing 3: 10x - 8y + 3.
So it goes like this:
9y = 2x
2x = 10x - 8y + 3
Therefore, 9y = 10x - 8y + 3
