Question 172652: I submitted this question a little earlier. This is the first time I have ever used this site. It is great; thank you! I just read how you like to see work. Anyway, I did not do that. So here is the question again: The sum of the three digits is 12. The tens digit exceeds the hundreds digit by the same amount that the units digit exceeds the tens digit. If the digits are reversed, the new number exceeds the original number by 198. Find the original number. Here is my work: H + T + U = 12. (100u + 10t + h) - (100H + 10T + u) = 198. The example in the textbook is simple. This is more complicated. I've been working at it for some time. I appreciate you help so much!

Question 172704: I have a word problem that has been driving me crazy all night. I believe I have my setups, but I'm not sure. A number between 300 and 400 is forty times the sum of its digits. The tens digit is 6 more than the units digit. Find the number. Here is my setups: 300 + 10t + u = 40 (h + t + u), t = u + 6. Somewhere in figuring I get lost. Thanks for any help you can give.
