I need help with these problems:

1) A vending machine takes only nickels and dimes. There are 5 times as many dimes as nickels in the machine. The face value of the coins is $4.40. How many of each coin are in the machine?

2) A vending machine takes only nickels and dimes. At the end of the day there were 3 times as many nickels as dimes and a total of $25. How much of each coin were in the machine?

I know that there should be two equations for each problem. But I just don't know what the equations will be.

Please help.
