    Let us denote the years of Mary with M and the years that Al have with A.

    We know that the sum of Mary and Al's age is 48. So, we can write:

    M+A=48 (1)

    We also know that twelve years ago, Mary was twice as old as Al. So we can write:

    M-12=2*A (2)

    From the first equation (1) : M=48-A

    Let put this in the second equation:

    48-A-12=2A

    36=3A

    A=12

    M=48-12=36
