Let's call the numbers x and y. We know that the difference between the two numbers is 5, so we can write one equation as:

x - y = 5

We also know that the sum of the two numbers is 19, so we can write another equation as:

x + y = 19

We can solve this system of equations by adding the two equations together:

(x - y) + (x + y) = 5 + 19
2x = 24

We can divide both sides of the equation by 2 to solve for x:

x = 12

Now, we can substitute this value back into one of the original equations to solve for y:

12 + y = 19
y = 19 - 12
y = 7

Therefore, the two numbers are 12 and 7.
