Michael has $2.35 in dimes and nickles. He has a totoal of 29 coins. How many of each does he have?
---------
Quantity Eq::: n + d = 29 coins
Value Eq::::: 5n +10d = 235 cents
---------------------------------------
Divide thru the bottom equation by 5:
n + d = 29
n + 2d = 47
----
Subtract and solve for "d":
d = 18 (# of dimes)
-----
Solve for "n" using n + d = 29
n + 18 = 29
n = 11 (# of nickels)
