I have $3.50 dollars worth of dimes and nickels in my pocket there are 34 coins in total how many of each coin do I have

Answer 1

There is something wrong with the problem.

Since ... with 34 dimes at most you get $3.40, and any combination with nickels will lessen that dollar amount, with 34 nickels, at most you get, $1.70.

32 dimes + 2 nickels = $3.30

24 dimes and ten nickels give you 34 coins = 2.40.

30 dimes =$3.00; 4 nickels = 20. 3.20

28 dimes = 2.80. 6 nickels = 30 3.10

Answer 2

N + D = 34

.05N + .1D = 3.5

Multiply 1st equation by 5 and 2nd equation by 100

5N + 5D = 170

5N + 10D = 350

Subtract

5D = 180

Whoops?
