Problem number: 39.1 (d).
ODE order: 1.
ODE degree: 1.
The type(s) of ODE detected by this program : "system of linear ODEs" Unable to solve or complete the solution.
Solve \begin {align*} x^{\prime }\left (t \right )&=x \left (t \right ) y \left (t \right )-6 y \left (t \right )\\ y^{\prime }\left (t \right )&=x \left (t \right )-y \left (t \right )-5 \end {align*}
Does not currently support non linear system of equations. This is the phase plot of the system.
✗ Solution by Maple
dsolve([diff(x(t),t)=x(t)*y(t)-6*y(t),diff(y(t),t)=x(t)-y(t)-5],singsol=all)
\[ \text {No solution found} \]
