Predator$-$Prey problem. The following system $is$ a model for a population $of$ prey and

predators. Here, $x(t)is$ a population $of$ rabbits, $y(t)is$ a population $of$ foxes:

$\frac{dx}{dt}=2x-3xy$

$\frac{dy}{dt}=-3y+xy$

$(a)$ Interpret the equation $by$ considering the following questions.

What happens $to$ the rabbits $in$ the $absenceof$ foxes?

What happens $to$ the foxes $in$ the $absenceof$ rabbits?

What happens $to$ the rabbits and $to$ the foxes when the two interact?

$(b)$ Find all equilibria and classify them.
