0.10 x+0.20 y=0.18(x+y)Clayton will mix x milliliters of a 10 % by mass saline solution with y milliliters of a 20 % by mass saline solution in order to create an 18 % by mass saline solution. The equation above represents this situation. If Clayton uses 100 milliliters of the 20 % by mass saline solution, how many milliliters of the 10 % by mass saline solution must he use?
