Question 964966: I have to come up with 3 equations to solve for each coin.
There are 19 coins consisting of nickels, dimes & quarters. The total of the 19 coins equals $2. There are twice as many nickels as there are dimes. How many of each coin is there?
The first equation should be 5n+10d+25q=200...having trouble coming up with the third equation to show that there are twice as many nickels than dimes.
