Ответ:
We can solve by substitution. Let's solve for x in the second equation:
Replace every x in the first equation by that:
Now, plug that in for y in second equation and solve for x:
Since x was the number of birds and y was the number of cats in the store, there are 35 birds and 17 cats in the store.
