student : A chemist mixed a 15% glucose solution with a 35% glucose solution. This Mixture produced 35 liters of a 19% glucose solution. How many liters of each solution did the chemist use?
tutorsd6 : let me read
tutorsd6 : let 15 % glucose solution = x l and the 35 % glucose solution = ( 35 - x ) l
tutorsd6 : 15 % of x + 35% of ( 35 - x ) = 19 % of 35
student : okay thank you
student : i need this in a system.
tutorsd6 : 0.15x + 0.35 ( 35 - x ) = 0.19 * 35
student : a system
student : !!!!!!!!11
tutorsd6 : a system ? means ? can not follow ............
tutorsd6 : 0.15 x + 12.25 - 0.35x = 6.65
