Mathematica: cpu = 0.005001 (sec), leaf count = 31 $$\left\{\{x(t)\to c_{1}t+\frac{c_2}{t},y(t)\to \frac{c_2}{t}-c_{1}t\}\right\}$$

Maple: cpu = 0.032 (sec), leaf count = 31 $$\left\{\{x\left(t\right)=\frac{\mathit{\_}\mathit{C}\mathit{2}{t}^2+\mathit{\_}\mathit{C}\mathit{1}}{t},y\left(t\right)=\frac{-\mathit{\_}\mathit{C}\mathit{2}{t}^2+\mathit{\_}\mathit{C}\mathit{1}}{t}\}\right\}$$
