Solve \begin {align*} x^{\prime }\left (t \right )&=-x \left (t \right ) y \left (t \right )^{2}+x \left (t \right )+y \left (t \right )\\ y^{\prime }\left (t \right )&=x \left (t \right )^{2} y \left (t \right )-x \left (t \right )-y \left (t \right )\\ z^{\prime }\left (t \right )&=y \left (t \right )^{2}-x \left (t \right )^{2} \end {align*}

Solution by Maple

dsolve([diff(x(t),t)=-x(t)*y(t)^2+x(t)+y(t),diff(y(t),t)=x(t)^2*y(t)-x(t)-y(t),diff(z(t),t)=y(t)^2-x(t)^2],singsol=all)
