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 )-x \left (t \right ) z \left (t \right )\\ y^{\prime }\left (t \right )&=-x \left (t \right ) y \left (t \right )+y \left (t \right ) z \left (t \right )\\ z^{\prime }\left (t \right )&=x \left (t \right ) z \left (t \right )-y \left (t \right ) z \left (t \right ) \end {align*}

Does not currently support non linear system of first order linear differential equations.

Solution by Maple

dsolve([diff(x(t),t)=x(t)*(y(t)-z(t)),diff(y(t),t)=y(t)*(z(t)-x(t)),diff(z(t),t)=z(t)*(x(t)-y(t))],singsol=all)
