Question 570454: Suppose that Maria has 140 coins consisting of pennies, nickels, and dimes. The number of nickels she has is 15 less than twice the number of pennies; the number of dimes she has is 25 less than three times the number of pennies. How many coins of each kind does she have? (I have tried to translate into an equation, but it doesn't work. I had 2n-15 + 3n-25. I am not sure how to do this problem)

Question 567635: Hi I am trying to help my daughter with her math homework and I know the answer to the question but I am really not sure how I came up with it. Here is the question.
Victor has 8 coins. He has 2 fewer dimes than nickels, and one more penny than nickels. How much money does he have?
In my head I figured out that there is going to be 1 dime, 3 nickels, and 4 pennies and that would of course equal 29 cents. Unfortunately we have to explain our answer and show the work and that is where I am stuck.
Thanks for your help!
