Hi,

The sum of three whole numbers is 7. 

The second number is 1 more than the twice of the third numberhighlight_green%28x%29.

third number  highlight_green%28x%29.

second number highlight_green%282x%2B1%29

first number  highlight_green%287+-%28+2x%2B1%29-x%29 0r  (6 - 3x)

Question states***sum of first and third number is 3 less than the second number

 (6-3x) + x = (2x+1) - 3

   6 -2x = 2x-2

    8 = 4x

    2 = x, the third number

third number  highlight_green%282%29.

second number highlight_green%285%29

first number  highlight_green%280%29
