Now, let's do the same as we did for the previous one here.

notice again, how did we get 84 for the 4th element's coefficient? well 36 * 7 / 3. and so on. And you can just expand it from there.
Answer:
x = 72
Step-by-step explanation:
2/3x + 6 = 1/2x + 1/4x
2/3x + 6 = 3/4x
3/4 - 2/3 = 1/12
6 = 1/12x
Multiply 6 by 12 to get x
x = 72
3a(4a²-5a+12)
12a³-15a²+36a
