draw two intersecting circles inside a rectangle, label them F and G, and label the rectangle U for universal set
Place x in the intersection, since you don't know that
Place 19-x in the F only section
Place 25-x in the G only section
place 5 inside the rectangle but outside the circles.
39-x + x + 25-x + 5 = 39
solve for x , to find how many take both subjects
