Answer:
![n = - (4)/(3)](https://img.qammunity.org/2021/formulas/mathematics/college/fm9cikctif0d4i6tno6bbg5wbw7c6kbk3r.png)
Explanation:
![8 = - 18 + (3)/(8) (16 - 40n)](https://img.qammunity.org/2021/formulas/mathematics/college/6wlwamkiq33yxikla05tb7dff2pbq6cw.png)
Multiply the terms in the bracket
That's
8 = - 18 + 6 - 15n
-12 - 15n = 8
Using the addition property add 12 to both sides
That's
12 - 12n - 15n = 8 + 12
- 15n = 20
Divide both sides by - 15
That's
![- (15n)/( - 15) = ( 20)/( - 15)](https://img.qammunity.org/2021/formulas/mathematics/college/pg36zgt7j04ax3ishcsnx0kj7mh6rcocx8.png)
Reduce the fraction with 5
We have the final answer as
![n = - ( 4)/(3)](https://img.qammunity.org/2021/formulas/mathematics/college/hfnqw1pd5lx66w1o9lk4zaf6w3b6ya6hkq.png)
