    Step-by-step explanation:

    As, they all are consecutive and odd

    The equation = x + (x + 2) + (x + 4) = 39

    X represent the first number and also the smallest one

    X + 2 is the 2nd number, it’s consecutive and odd so we need to add 2

    X + 4 is the 3rd number, it’s consecutive and odd to (x+2) so we will just add 2 more = x + 2 +2 = x +4

    So x + (x + 2) + (x + 4) = 39

    3x + 6 = 39

    3x = 39 – 6

    3x = 33

    x = 11

    So smallest number = 11

    And x + 2 = 11+2 = 13 (second number)

    And x + 4 = 11 + 4 = 15 ( third number )

    So only because u asked for the smallest

    So it’s 11
