*THE ANSWER SHOULD BE POSITIVE SIGN ONLY!*
Explanation:
First, you multiply by 10 from both sides of an equation.
![0.5n*10=12.5*10](https://img.qammunity.org/2020/formulas/mathematics/middle-school/bhwzuhzioj1jkwqeadh9hklvbct359spk4.png)
Multiply by the numbers or decimals from left/right.
![12.5*10=125](https://img.qammunity.org/2020/formulas/mathematics/middle-school/tkbscic2t06t0bgm8lbl5nycmt70ejfvol.png)
![5n=125](https://img.qammunity.org/2020/formulas/mathematics/middle-school/7fycwc0kdzne5ddkhe3gmznpr23y725eb2.png)
Then, you divide by 5 from both sides of an equation.
![(5n)/(5)=(125)/(5)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/n32y1yvjqibqo7fv4gk9bpwk8r6z0858gg.png)
Divide by the numbers from left/right.
![125/5=25](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ywpajtyv5r3c0pyjhpy6x8twl4k7z9f1it.png)
, is the FINAL/CORRECT ANSWER!
