Answer:
Step-by-step explanation:
Let 25% solution is x liters, then 50% solution is (80 - x) liters.
<u>Acid content is going to be same:</u>
- 0.25x + 0.5(80 - x) = 80*0.4
- 0.25x - 0.5x + 40 = 32
- 0.25x = 8
- x = 8/0.25
- x = 32 liters
So 32 liters of 25% solution and 80 - 32 = 48 liters of 50% solution

Answer:
y = ![\frac{5x-11}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B5x-11%7D%7B8%7D)
Step-by-step explanation:
Given
5x - 8y = 11 ( subtract 5x from both sides )
- 8y = 11 - 5x ( multiply through by - 1 )
8y = - 11 + 5x = 5x - 11 ( divide both sides by 8 )
y = ![\frac{5x-11}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B5x-11%7D%7B8%7D)
