Question 197810: Kathy has 5 liters of 32% acid solution and she also has a large amount of a 26% acid solution. How many liters of the 26% solution can Kathy mix with the 5 liters of 32% solution in order to produce a 50% acid solution? I know that there is no solution due to the fact that combining solutions of 26% and 32% will never create a solution of greater concentration then 32% however I need to know how to set up the system of equations to solve this problem regardless of the outcome. What are the two equations?

Quality Equation:
acid + acid = acid
0.32*5 + 0.26x = 0.50y
