Question

Use two variables and two equations. Solve by any method you choose. Write your answer in the appropriate form.

A lady has 11 animals. Some are cats and some are birds. If there are 34 legs among all her animals, how many animals does she have?

Answer 1

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?

Answer 2

eliminate one of the variable and you are good to solve it

Answer 3

or you can also use the substitution method

Answer 4

im lost

Answer 5

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 ?
