    Let s be the number of student tickets.

    Let a be the number of adult tickets.

    s + a = 394

    s = a - 56

    Substitute a-56 in equation 1.

    a - 56 + a = 394

    2a - 56 = 394

    2a = 450

    a = 225 tickets

    So you can do this by using a system of equations

    x=student tickets

    y=adult tickets

    x+y=394

    x+56=y

    then you substitute y in

    x + (x+56) = 394

    2x+56=394

    2x=394-56

    2x=338

    x=169 which is the number of student tickets

    then you find the amount of adult tickets

    x+56=y

    169+56=y

    225=y

    and now you can check it

    225+169=394

    394=394

    Answer:

    169 student tickets were sold

    225 adult tickets were sold
