    Answer: 9, 11, 13

    Step-by-step explanation:

    Let x, y, and z represent the odd integers:

    x + 2y + 3z = 70

    You need another clue to answer this question. Let's assume they are consecutive odd integers. Then: y = x + 2 and z = x + 4

    Use substitution and solve for x:

    x + 2 (x + 2) + 3 (x + 4) = 70

    x + 2x + 4 + 3x + 12 = 70

    6x + 16 = 70

    6x = 54

    x = 9

    y = x + 2 z = x + 4

    = 9 + 2 = 9 + 4

    = 11 = 13

    So, the three consecutive odd integers are: 9, 11, & 13
