    Let the first number be x and;

    The second number be y.

    So:

    x + y = 137 ... (i)

    x - y = 17 ... (ii)

    Solving this set of simultaneous equations by elimination:

    We add (i) to (ii) to get;

    2x + 0 = 154

    2x = 154, x = 154/2 = 77

    y = 77 - 17 = 60

    So the first number is 77

    And the second number is 60.

    If a and b are the numbers, a+b=137; and a=b+17.

    So a-b=17. Add two equations together: (a+b) + (a-b) = 137+17=154 and 2a=154, making a=77.

    If a=77 b must be 137-77=60.

    The two numbers are 77 and 60.
