I am wondering if the wording of this problem and/or the use of parenthesis is what is causing you confusion? I will give you a few hints to assist you based on errors/steps where students get confused when presented with something like this.
Lets Back up here:
- If the problem where simply "worded expand" the following using the distributive property what would you do?
a. Would you know how to set up the problem? Still Stuck?
b. Lets back up even further. Would you known how to solve the following problem if it asked you to distribute or expand the following expression?
-8(m-3+4n)
Hint: the above expression is simply the problem rearranged. However, this is just the start of the problem you must finish it!
Let me know if you can take it from here or you are still stuck/need more hints
