You can put this solution on YOUR website!
Let n = number of nickels she has
Let d = number of dimes she has
given:
+d+=+5n+
+10d+%2B+5n+=+330+ (in cents)
------------------
Use substitution
10%2A5n+%2B+5n+=+330+
+50n+%2B+5n+=+330+
+55n+=+330+
+5n+=+30+
+n+=+6+
and
d+=+5n
+d+=+5%2A6
d+=+30
She has 6 nickels and 30 dimes
