    There are 6,296 children at the carnival

    Step-by-step explanation:

    The number of each group of people can be expressed as;

    Number of boys (b) + number of adults (a) = 7,052

    b+a=7,052 ... equation 1

    Number of girls (g) = Number of adults (a) - 756

    g=a-756 ... equation 2

    But Number of girls (g) = number of boys (b)

    Replacing the value of b in equation 1 with that of g in equation 2;

    (a-756) + a=7,052

    a+a=7,052+756

    2 a=7,808

    a=7,808/2

    a=3,904

    Replace the value of a in equation 2 with 3,904

    g=3,904-756

    g=3,148

    But since g=b

    g=b=3,148

    b=3,148

    Total number of children=Total number of boys (b) + total number of girls (g)

    Total number of children=b+g

    where;

    b=3,148

    g=3,148

    replacing;

    Total number of children = (3,148+3,148) = 6,296

    There are 6,296 children at the carnival
