SOLUTION: a 60% saline solution is to be mixed with an 80% saline solution to get 40 liters of a 65% saline solution. how many liters of the 60% and 80% solution should be used

Question 925090: a 60% saline solution is to be mixed with an 80% saline solution to get 40 liters of a 65% saline solution. how many liters of the 60% and 80% solution should be used
Answer by TimothyLamb(4379) (Show Source): You can put this solution on YOUR website!
x = liters of 60% solution
y = liters of 80% solution
---
60x + 80y = 65*40
x + y = 40
---
put the system of linear equations into standard form
---
60x + 80y = 2600
x + y = 40
---
copy and paste the above standard form linear equations in to this solver:
