Question 822542: You are a lab assistant for Dr. Shay. In the lab, he has two solutions. Solution A is a 10% alcohol solution and Solution B is a 40% alcohol solution. For a lab project, students will need to have 5 liters available of a 19% alcohol solution. How many liters are each solution to you need to mix together to help Dr. Shay get ready for lab

---
10x + 40y = 19*5
x + y = 5
---
put the system of linear equations into standard form
---
10x + 40y = 95
x + y = 5
---
copy and paste the above standard form linear equations in to this solver:
