    Hello,

    Imagine Algebra does not exist .

    Let’s suppose all tickets are children’s tickets

    The sum should be 5$*375=1875$

    Not enough, we must have $2153: 2153-1875=278 ($) must be found.

    Let’s replace a children ticket with an adult one,

    we get one dollar more.

    We must thus exchange 278 tickets

    There are 278 adult tickets and 375-278=97 children tickets

    Proof:  278*6+97*5=2153
