anonymous · Answer

cats=x
birds=y
total animal = 11 = x+y
total legs      = 34= 4x+2y
if you solve this you can manage to tell how many cats and birds she have?

im lost

texaschic101 · Answer

cats = x
birds = y

x + y = 11 --->x = 11 - y
4x + 2y = 34

now sub 11 - y in for x in the second equation :
4x + 2y = 34
4(11 - y) + 2y = 34

can you take it from here ?
