<u>So with more than one pair of parentheses, you must start from the inside and make your way outside.</u>
So firstly, distribute -3 to (2x + 4):
![6+2[-8-6x-12]+10x](https://tex.z-dn.net/?f=6%2B2%5B-8-6x-12%5D%2B10x)
Next, combine like terms:
![6+2[-6x-20]+10x](https://tex.z-dn.net/?f=6%2B2%5B-6x-20%5D%2B10x)
Next, distribute 2 to [-6x - 20]:

Lastly, combine like terms and <u>your final answer will be
