    Let's call the numbers x (the bigger) and y (the smaller)

    The larger of two integers is 8 less than twice the smaller. this means:

    x=2z-8

    When the smaller number is subtracted from the larger, the difference is 17.

    This means: x-z=17.

    i'll insert

    2z-8

    instead of x, since it's equal to it:

    2z-8-z=17

    2z-z is just z:

    z-8=17

    so

    z=25.

    and x must be 25+17=42

    let's check:The larger of two integers is 8 less than twice the smaller.

    twice the smaller is 50, and yes, 42 is 8 smaller than 50, it's correct!

    so the two numbers are 25 and 42
