Answer:
Max exercises 13 hours a week, and Sasha 7.
Step-by-step explanation:
To find the number of hours each of them exercises during the week, we solve the system of equations.
In the second equation:
![x = 4y - 15](https://tex.z-dn.net/?f=x%20%3D%204y%20-%2015)
Replacing in the first equation:
![x + y = 20](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%2020)
![4y - 15 + y = 20](https://tex.z-dn.net/?f=4y%20-%2015%20%2B%20y%20%3D%2020)
![5y = 35](https://tex.z-dn.net/?f=5y%20%3D%2035)
![y = \frac{35}{5}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B35%7D%7B5%7D)
![y = 7](https://tex.z-dn.net/?f=y%20%3D%207)
So Sasha exercises 7 hours per week.
Max:
![x + y = 20](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%2020)
![x + 7 = 20](https://tex.z-dn.net/?f=x%20%2B%207%20%3D%2020)
![x = 13](https://tex.z-dn.net/?f=x%20%3D%2013)
Max exercises 13 hours a week.
