The numbers which go into 39 are the factors of 39 which are: 1, 3, 13, 39. Any of its factors which are: 1, 3, 13 and 39
Oh, what a happy little question! Let's see, for 39, you can divide it by 1, 3, 13, and 39. And for 100, you can divide it by 1, 2, 4, 5, 10, 20, 25, 50, and 100. Remember, there are no mistakes in math, just happy little numbers finding their place.
let x be one number and y be the other The first thing given is that x is 3 less than twice y so x=2y-3 and x+y=39 so x=39-y and substitute this into the first equation a 39-y=2y-3 42=3y y=14 and x=39-14 or 25 Answer x=25 and y=14 Now lets check it 25 is 3 less than 2x14 (YES) 14+25=39 (YES) Done
