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? Enter your answers, as decimals, in the boxes.

so.. whatever the sum of "x" and "y" is, it must come with a 10Liter
solution of 10% or 10/100 = 0.10 acidity
thus
solve for "y" to see how much of the 25% solution must be used,
how much "x" will it be? well x = 10 -y :)
