A chemist is preparing two solutions of a chemical, Solution A and Solution B. Solution A consists of 10% chemical concentration, while Solution B has a 25% concentration. The chemist aims to combine these solutions to get exactly 50 mL of a solution that has a chemical concentration of 20%.
Let x represent the volume of Solution A in milliliters, and y represent the volume of Solution B in milliliters. The following conditions must be met:
What is the value of y?
