Dave is put in a cell with a dirt floor and only one window.
The window is too high for him to reach.
The only thing in the cell is a shovel.
He won't be able to get any food or water and only has two days to escape or he'll die.
Dave can't dig a tunnel because it will take him much longer than two days to do it.
How will Dave escape from the cell?
Dave has to use the shovel to create a pile of dirt under the window so he can climb up onto it and escape from the cell.

There are several chickens and rabbits in a cage (with no other types of animals). There are 72 heads and 200 feet inside the cage. How many chickens are there, and how many rabbits?
There are 44 chickens and 28 rabbits in the cage.
Let c be the number of chickens, and r be the number of rabbits.
r + c = 72
4r + 2c = 200
To solve the equations, we multiply the first by two, then subtract the second.
2r + 2c = 144
2r = 56
r = 28
c = 44
