Final Correct Answer:
14n - 16g + 8
Hope this helps :)
Error:
The error was that I'm the first step where they distributed -4 to the numbers - 3n, + 4g, - 2 wrong. They multiplied with the wrong integer rules.
Real answer - how to solve:
- 4 multiply by - 3n would be + 12n (Negative times Negative equals Positive).
-4 multiply by + 4g would be - 16g (Negative times Positive equals Negative).
- 4 multiply by - 2 would be + 8 (Negative times Negative equals Positive).
So that was the error.
Step-by-step explanation:
1. Distribute.
2n - 4( - 3n + 4g - 2)
2n + 12n - 16g + 8
2. Combine Like Terms (CLT).
2n + 12n - 16g + 8
14n - 16g + 8
