Answer:

We are given the following:
In order to solve for this equation, we have to use the 7 to plug in to the numbers in the parentheses, and then simplify everything from there.
- Simplifying 7 with 2n and -4 gives us an equation of

- This equation can still be simplified specifically the -28 and the positive 5. -28 + 5 Is -23
- Lastly when we put the equation altogether we have:
since there are no more like terms, the equation can no longer be simplified.
