Question 417184
A farmer has cows and chickens. Juan counted 296 legs in the farmyard. If there are 100 animals, how many are cows and how many are chickens
----
animal equation: w + h = 100
legs equation:  4w + 2h = 296
----
Multiply thru the 1st by 2 to get:
2w + 2h = 200
4w + 2h = 296
----
Subtract and solve for "w':
2w = 96
w = 48 (# of cows)
---
100-48 = 52 (# of chickens)
