inicial
agua = 06*8 = 4.8 litros
cloro = 0.4*8 = 3.2 litros
Retirados x da mistura
Retirados
0.6x de água
0.4x de cloro
resto
4.8 - 0.6x agua
3.2 - 0.4x cloro
Aumento de x de cloro
agua (4.8 - 0.6x)
cloro (3.2 - 0.4x + x) = (3.2 + 0.6x)
agua
4.8 - 0.6x = 0.1*8 ---->
4.8 - 0.6x = 0.8 ---->
0.6x = 4.0
x = 4/0.6 = 4/6/10 = 40/6 = 20/3 L
cloro
(3.2 + 0.6x) = 0.9*8
3.2 + 0.6x = 7.2
0.6x = 4
