Let 'x' and 'y' represent the numbers.

One number is 3 more than twice another number:

y = 3 + 2x

The sum of the two numbers is 25:

x + y = 25

We need to solve the following system of equations to find the numbers:

y = 3 + 2x

x + y = 25

x = 22/3

x = 7 1/3

y = 53/3

y = 17 2/3

The numbers are 7 1/3 and 17 2/3.
