A chills bank contains 70 coins( dimes and nickels that value $5.55) how many of each coin
----
Equations:
Quantity: n + d = 70
Value::: 5n+10d = 555 cents
-------------------------------
Divide thru the Value equation by 5:
n + d = 70
n + 2d = 111
----
Subtract and solve for "d":
d = 41 (# of dimes)
----
Solve for "n":
n + d = 70
n + 41 = 70
n = 29 (# of nickels)
