    The first number is 8 and the second number is 3.

    Step-by-step explanation:

    Let the first and second numbers be represented by f and s.

    Then f + s = 11. Also, 2f + s = 19. Find f and s.

    Solving the first equation for s, we get s = 11 - f.

    Substituting this 11 - f for s in the second equation, we get:

    2f + 11 - f = 19

    Combining like terms,

    f = 8. Then s must be 3, since f + s = 11 = 8 + 3.

    The first number is 8 and the second number is 3.
