Question 15137: The second of three numbers is 8 more that the first and the third number is 3 less than 3 times the first. If the tird number is 15 more than the second, find the three numbers.
Here's what I have for the variables:
First number = x
Second number = x + 8
third number = 3x - 3 and it is x + 8 + 15
Where do I go from here?? Answer by venugopalramana(3286) (Show Source):
You can put this solution on YOUR website! The second of three numbers is 8 more that the first and the third number is 3 less than 3 times the first. If the tird number is 15 more than the second, find the three numbers.

OH!! DEAR!! DEAR!! YOU GOT IT !! YOU ARE ALMOST AT THE FINISH LINE !!! JUMP AHEAD ! YOU WILL GET THE ANSWER!!!
You rightly concluded that the third number is 3x-3 and it is x+8+15...MEANS WHAT ???? THEY ARE EQUAL ...SO
3x-3=x+8+15
3x-x=8+15+3
2x=26...or x=13..... hence the 3 numbers are as per your own working
First number = x =13
Second number = x + 8=13+8 =21
third number = 3x - 3=3*13-3=36..check this if you want with
x + 8 + 15 = 13+8+15 =36
