Step-by-step explanation:
1 week = 7 days
given 7 days = 14 hours of practice
and let x be the number of hours spent on practicing and y the number of days.
from the above expression we can have the equation,
![y = \frac{x}{2}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7Bx%7D%7B2%7D%20)
using the equation when y = 10,
![\frac{x}{2} = 10 \\ x = 2(10) \\ = 20](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B2%7D%20%20%3D%2010%20%5C%5C%20x%20%3D%202%2810%29%20%5C%5C%20%20%3D%2020)
Answer:
