Question 99717: While Michelle sat observing birds at a bird feeder, one fourth of the birds flew away when they were startled by a noise. Two birds left the feeder to go to another stationed a few feet away. Three more birds flew into the branches of a nearby tree. Four birds remained at the feeder. How many birds were at the feeder initially? Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! let x=number of birds initially
x-x/4-2-3=4
multiply 4 times each side: 4x-x-8-12=16
3x-20=16
add 20 to each side: 3x=36
divide 3 into each side: x=12 bird originally at the feeder.
Check:
12-12/4-2-3=4
12-3-2-3=4 true
