    The three integers are 13,14,15

    Step-by-step explanation:

    Let x be the first integer

    x+1 be the second integer

    x+2 be the third integer

    The sum of the three integers is 42

    x + (x+1) + (x+2) = 42

    Combine like terms

    3x+3 = 42

    Subtract 3 from each side

    3x+3-3 = 42-3

    3x = 39

    Divide by 3

    3x/3 = 39/3

    x = 13

    x+1 = 14

    x+2 = 15

    The three integers are 13,14,15
