X + y = 25
      y = 25 - x
where the first polygon's sides are greater than the second polygon.

The representation for each side of polygon:
first polygon             x
second polygon       25-x
total number of sides of the two polygons = 25

If first polygon (x) is 16-sided,
then the second polygon (25-16) is 9-sided.
              16 + 9 = 25

If first polygon is 14-sided,
then the second polygon (25-14) is 11-sided.
               14 + 11 = 25

The given problem requires another condition so we can solve for the specific value of x.

Example 1:  The total number of sides of the two polygons is 25.  The sum of their diagonals is 131.

Example 2:  The total number of sides of the two polygons is 25.  One polygon has 2 more than twice the numbers of sides of the other polygon.
