There are a total of 26 nickels and dimes in a piggy bank. The value of the coins is $1.65. How many nickels and dimes are there in the piggy bank?
--------------------------------------
Quantity Eq::: n + d = 26
Value Equat:::5n +10d= 165 cents
-----
Multiply thru the Quantity Eq by 5 to get:
5n + 5d = 5*26
----
Subtract that equation from the value equation to get:
5d = 35
d = 7 (# of dimes)
-------
Since n+d = 26, n = 19 (# of nickels)
