1. Problem in Latex
2. Mathematica input
3. Maple input

Mathematica: cpu = 0.005001 (sec), leaf count = 22 $$\left\{\{x(t)\to c_1{e}^{at},y(t)\to bt+c_2\}\right\}$$

Maple: cpu = 0.015 (sec), leaf count = 19 $$\left\{\{x\left(t\right)=\mathit{\_}\mathit{C}\mathit{1}{\mathrm{e}}^{at},y\left(t\right)=bt+\mathit{\_}\mathit{C}\mathit{2}\}\right\}$$
