There are 15 animals in a barn. These animals are horses and chickens. Write an equation for the situation.

Each chicken has 2 legs. Each horse has 4 legs. There are a total of 44 legs. Write an equation for the situation.

There are 15 animals in a barn. These animals are horses and chickens. Horses have 4 legs, chickens have 2 legs. There are 44 legs in all. Which system of equations represents the situation?

• x + y = 15

  4x + 2y = 44

• 4x + 2y = 15

  x + y = 44

• x = 2y + 44

  4x = y + 15

• 2x - 4y = 44

  x - y = 15
