To learn how to set up and solve this sort of exercise, please try here. Study at least two lessons from the list at the link. Once you have learned the basic terms and techniques, please attempt at least one of the exercises you have posted. If you get stuck, you can then reply with a clear listing of your efforts so far.

Thank you! ;)

This has infinitely many solutions because you have three unknown values, the number of nickels, the number of dimes, and the number of quarters. But you have only two conditions. Is it possible that the word "nickels" should be dimes or vice-versa?

Assuming that 'nickels' means dimes. For problem 1, the equation would be 0.25x = 0.10x + 9 . X turns out to be 60. So theres 60 quarters, 60 dimes and $9 worth of more dimes. So the final solution is 60 quarters and 150 dimes.
