The positive parameters $ \lambda $, $ q $ satisfy $ 0 &lt; \lambda &lt; \infty $, $ 1 &lt; q &lt; 2 $, and $ p_{1} $, $ p_{2} &gt; 1 $ with $ p_{1}+p_{2} = 2^*(\gamma) $, here $ 2^*(\alpha): = \frac{2(Q-\alpha)}{Q-2} $, $ 2^*(\beta): = \frac{2(Q-\beta)}{Q-2} $ and $ 2^*(\gamma) = \frac{2(Q-\gamma)}{Q-2} $ are the critical Hardy-Sobolev exponents, $ Q $ is the homogeneous dimension of the space $ \mathbb{G} $. By means of variational methods and the mountain-pass theorem of Ambrosetti and Rabonowitz, we study the existence of multiple solutions to the sub-elliptic system.</p>
