This example, he is supplied with 48% and 26% solutions; and he wants to make 44 liters of 32% solution.

Final concentration needs to be 32%, or 0.32 in decimal fraction.
If variable v is for the amount of 48% solution to use, then 44-v is the amount of the 26% solution to use.

To account for the PURE amount of substance in the solutions:

Now solve for v.

-----------liters of the 48%
-
-------------liters of the 26%
