Esmeralda had 28 coins, made up of nickels(x), dimes(y) and quarters(z). if she had two more nickels, she would have just as many nickels as she had dimes and quarters put together. If the total value of Esmeralda's coins is $3.20, how many coins of each kind does she have? hint: ( x + 2 = y + z)

• She has 13 nickels, 8 dimes and 7 quarters.

• She has 12 nickels, 3 dimes and 13 quarters.

• She has 11 nickels, 10 dimes and 7 quarters.

• She has 10 nickels, 6 dimes and 12 quarters.

• x = 3 is the real solution; x = -9 is the extraneous solution.

• x = 1 is the real solution; x = 3 is the extraneous solution.

• x = 3 is the real solution; x = 1 is the extraneous solution.

• x = 1 is the real solution; x = -9 is the extraneous solution.
