You take y liters of the solution and put it into a bucket or container. You then put y (same amount as before) liters of water in the same container, and voila! You now have a container with 50 percentile solution, 50 percentile water.
Let there be x litres of 50% solution and y% of 20 % solution, then you have two equations by considering the amount of alcohol and the total amount of liquid:50% x + 20% y = 40% of 3 litresx + y = 3 litresThese are two simultaneous equations involving 2 unknowns which can be solved:Double {1} and subtract from {2} to give:x - x + y - 40%y = 3 - 80% of 3→ 60% y = 20% of 3→ y = 20%/60% of 3 = 1/3 of 3 = 1Substitute for y in {2} to get:x + 1 = 3x = 2Therefore you need 2 litres of 50% solution and 1 litre of 20% solution.

the number 1 is the only solution. y-1 = 0 1-1 = 0 every single number except 1 is not a solution your domian would equal D=All Reals (such that y is not equal to 1)
