Question 379302
 miranda visited a petting zoo on saturday. she counted 95 ducks and goats.
she also counted 316 legs between the ducks and goats. how many of each kind of each animal did miranda see?
------------------------
Equations:
Heads: d + g = 95
Legs::2d +4g = 316
------------------------
Multiply thru the 1st equation by 2 to get:
2d + 2g = 190
------
Subtract that from the Legs equation and solve for "g":
2g = 126
g = 63 (# of goats)
---
Since d+g = 95, d = 32 (# of ducks)
----
