    Using algebra, we can say that the first number is x, and the second number is y.

    x+y=90

    x-y=12

    Adding these two equations gives us:

    2x=102

    x=51

    Plugging this into the first equation,

    51+y=90

    y=39.

    So, the two numbers are 51 and 39.

    39 and 51

    The way to figure this out is to divide 90 by two

    45 now subtract six and add six to 45 to achieve a difference of 12

    45 - 6 = 39

    45 + 6 = 51
