Answer: The three numbers are 10, 11, and 12.
10+11+12 = 33
=========================================================
Work Shown:
- x = smallest number
- x+1 = middle number
- x+2 = largest number
Each is a positive whole number
Add them up and set the result equal to 33. Solve for x.
(x) + (x+1) + (x+2) = 33
3x+3 = 33
3x+3-3 = 33-3 .... subtract 3 from both sides
3x = 30
3x/3 = 30/3 ..... divide both sides by 3
x = 10
x+1 = 10+1 = 11
x+2 = 10+2 = 12
Note how 10+11+12 = 33 to help confirm our answer.
