    2, 4 and 6 are consecutive even integers that fit the criterion.

    Step-by-step explanation:

    Model the problem as an equation

    let a be first integer, b be second, c be third

    8a = b+c+6

    Since these are consecutive even integers:

    b = a + 2

    c = b + 2 = a + 4

    Substitute these equivalents into the equation

    8a = (a+2) + (a+4) + 6

    Combine like terms

    8a = a+2+a+4+6

    8a = 2a + 12

    Isolate a

    6a = 12 (divide both sides by 6)

    a = 2

    Sub a=2 into b=a+2 and c=a+4

    b=a+2 = 2+2 = 4

    b=4

    c=a+4 = 2+4 = 6

    c=6
