The first answer because you have to write 3x/ x-4 as a denominator, then you have to keep simplifying

Answer: 3rd option

Step-by-step explanation:

Let’s look at the denominator. 2x-yep. (x-4) is also there.

There is 2 “x” denominators and 3 + 4 = 7. So it’ll look like 7x*2.

Then, there needs to be an + and - sign in the answer.

Finally, the third option is the only one that incorporates all three factors.

Hope this helps!
