Here is how we do it:
First, we must simplify 4/5n to 4n/5.
Then we simplify:
to get
![2n/3.](https://img.qammunity.org/2020/formulas/mathematics/high-school/8natf5n4cnmj174qiyw03uduj1v8hjnvil.png)
After we multiply both sides by the number 15.
![12n = 10n](https://img.qammunity.org/2020/formulas/mathematics/high-school/qihnd9dz169x4km2pqy8yjyvf4sbhn4tup.png)
Alright, now let's move them all together.
It would be:
![12n - 10n = 0](https://img.qammunity.org/2020/formulas/mathematics/high-school/2f6umfly5miuv945rxucwei9ff01l2mqev.png)
Our last step is to simplify 12n - 10n to 2n.
Then we receive:
![2n = 0](https://img.qammunity.org/2020/formulas/mathematics/high-school/hdkf21blccj46jhldrekh8h4jkk4lzn03x.png)
After we divide both sides by 2.
Our final answer is:
