Question 931749: Marie mixes 16 liters of 78% acid solution with a 25% acid solution to make a 41% acid solution.
How many liters of 25% solution did she use?
You can put this solution on YOUR website! x = liters of 78%
y = liters of 25%
---
x + y = 16
78x + 25y = 41*16
---
put the system of linear equations into standard form
---
x + y = 16
78x + 25y = 656
---
copy and paste the above standard form linear equations in to this solver:
