    90, 540, and 190

    Step-by-step explanation:

    To write an equation or expression for the numbers, first define the variables.

    The "first number" is x.

    "6 times a first number" is 6x. This is the second number.

    "100 more than the first number" is 100+x. This is the third number.

    All together, they add to 820.

    x+6x+100+x = 820

    8x + 100 = 820

    8x = 720

    x = 90

    So the first number is 90. The second number is 6x = 6*90 = 540. The third number is 100+x = 100+90 = 190.
