To determine the number of hamsters and ducks, we can set up a system of equations based on the given information.

Let x be the number of hamsters and y be the number of ducks.

We know that the total number of animals is 28. This information can be translated into the equation: x + y = 28

We also know that one hamsters has 4 legs and one ducks has 2 legs. Thus, the equation can be written as: 4x + 2y = 120, then

1. Solve the first equation for y: y = 28 - x
