Explanation:
The distributive property said that:
[tex]a\cdot b+c\cdot b=(a+c)\cdot b[/tex]The initial expression is:
- 4n - 3n + 4n - 7
So, like terms are -4n, -3n, and 4n. It means that when we apply the distributive property, we get:
[tex]\begin{gathered} -4n-3n+4n-7 \\ (-4-3+4)n-7 \\ -3n-7 \end{gathered}[/tex]Therefore, the simplified expression is: - 3n - 7
Answer: - 3n - 7
