    Answer:

    The total number of albums sold on the first day=34

    Step-by-step explanation:

    Derive expressions for the number of albums sold

    each day;

    Let;

    the total number of albums sold on the first day=x

    the total number of albums sold on the second day=y

    but,

    total number of albums sold on the second day is twice the total number of albums sold on the first day, therefor=, y=2×x= 2 x

    The total number of albums sold for the two days can be expressed as;

    Total sales=number sold on the first day+number sold on second day

    where;

    Total sales=102

    number sold on the first day=x

    number sold on second day= 2 x

    replacing;

    (x+2 x)=102

    3 x=102

    x=102/3

    x=34

    The total number of albums sold on the first day=34
