Alcohol solutions

We have to produce 2 liters of 60% alcohol from 55% and 80%. How many of which ones will we use in the solution?

Correct result:

a =  1.6 l
b =  0.4 l

Solution:

V=2 l    a+b=V 0.55a+0.80b=0.60 V a+b=2 0.55a+0.80b=0.60 2  a+b=2 0.55 a+0.80 b=0.60 2  a+b=2 0.55a+0.8b=1.2  a=85=1.6=85 l=1.6 l b=25=0.4
