50+2x=100
-50 -50(subtract 50 from both sides)
2x=50 (divide both sides by 2)
x=25

Answer:
The total fluid you have to drink is 10 7/10 = 10.7 cups.
Step-by-step explanation:
The daily requirement of water = 8 2/4 cups
Now, ![8 \frac{2}{4} = 8+ \frac{2}{4} = 8+ 0.5 = 8.5](https://tex.z-dn.net/?f=8%20%5Cfrac%7B2%7D%7B4%7D%20%20%3D%208%2B%20%20%5Cfrac%7B2%7D%7B4%7D%20%20%3D%208%2B%200.5%20%3D%208.5)
or, the daily water requirement = 8.5 cups
The daily requirement of milk = 2 1/5 cups
Now, ![2 \frac{1}{5} = 2+ \frac{1}{5} = 2+ 0.2 = 2.2](https://tex.z-dn.net/?f=2%20%5Cfrac%7B1%7D%7B5%7D%20%20%3D%202%2B%20%20%5Cfrac%7B1%7D%7B5%7D%20%20%3D%202%2B%200.2%20%3D%202.2)
or, the daily milk requirement = 2.2 cups
So, The total fluid needed = Cups of (Water + Milk) needed
= 8.5 cups + 2.2 cups
= 10.7 cups
Also, ![10.7 = 10 + 0.7 = 10 + \frac{7}{10} = 10\frac{7}{10}](https://tex.z-dn.net/?f=10.7%20%3D%2010%20%2B%200.7%20%3D%2010%20%2B%20%5Cfrac%7B7%7D%7B10%7D%20%20%3D%2010%5Cfrac%7B7%7D%7B10%7D)
Hence, the total fluid you have to drink is 10 7/10 cups.
