Answer by Jk22(389)   (Show Source):
You can put this solution on YOUR website! three times a number less four is 17
implies three times this number is 21 (17 plus four)
hence the number is twenty-one divided by 3, which is 7.
Formula wise : let x be the searched number, then
3x-4 = 17
3x = 17+4 = 21
x = 7
