Step-by-step explanation:

Let x represent the quantity of 25% solution to be used. Then 65-x is the quantity of 12% solution needed. The amount of alcohol in the mix is ...

  0.25x +0.12(65 -x) = 0.15(65)

  0.13x +7.8 = 9.75 . . . . eliminate parentheses

  0.13x = 1.95 . . . . . . subtract 7.8

  x = 15 . . . . . . . . . . . divide by .13

  65-x = 65-15 = 50

She needs 15 liters of 25% solution and 50 liters of 12% solution.
