### Solving a System of Differential Equations by Systematic EliminationWe aim to solve the given system of differential equations using systematic elimination. The system provided is:\[ (D + 1)x + (D - 1)y = 8 \]\[ 9x + (D + 8)y = -1 \]Here, \(D\) represents the differential operator \( \frac{d}{dt} \).### Step-by-Step Solution1. **Combine Equations**: Use systematic elimination to simplify the system.2. **Solve for Variables**: Find the solutions \( x(t) \) and \( y(t) \).The result will be expressed in the form:\[ (x(t), y(t)) = \left( \boxed{\phantom{x}} \right) \]### Explanation of the DiagramIn this context, there is no graph or diagram included that needs detailing. The focus is on transcribing the system of equations and the method to solve them.For a detailed and step-by-step solution, follow through with systematic elimination techniques in differential equations.

A forest is inhabited by rabbits and foxes. Every year, each rabbit gives birth to 7 babies and each fox gives birth to 2 babies on average. Foxes try to catch and eat rabbits; each month, each fox has a 3% chance of catching each of the rabbits present in the forest. Each month, every fox that does not eat a rabbit starves to death. Write the differential equations for the number of foxes and rabbits in the forest.
