Mathematica: cpu = 0.021503 (sec), leaf count = 29 $$\left\{\{y(x)\to c_1(-x)+c_{4}x+c_{1}x\log (x)-c_2\log (x)+c_3\}\right\}$$

Maple: cpu = 0.031 (sec), leaf count = 18 $$\{y\left(x\right)=\mathit{\_}\mathit{C}\mathit{1}x+\mathit{\_}\mathit{C}\mathit{2}x\ln \left(x\right)+\mathit{\_}\mathit{C}\mathit{3}+\mathit{\_}\mathit{C}\mathit{4}\ln \left(x\right)\}$$
