use a system of equations to solve this problem.
a chemist currently has two solutions of sodium chloride. one solution has a 5% concentration and the other has a 25% concentration. the chemist needs to make 10 l of a 10% sodium chloride solution.
let x = the amount of 5% solution.
let y = the amount of 25% solution.
how much of each solution does the chemist need to make?
