Why is maxima showing only [ ] as output answer?

Question

I'm new at using maxima, so when I wanted to solve these simultaneous equations $$y_1=-\left(\frac{2ax+c+ey}{2by+d+ex}\right)x_1+\left[y+\left(\frac{2ax+c+ey}{2by+d+ex}\right)x\right]$$ and, $$ax^2+by^2+cx+dy+exy+f=0$$ where the variables are $x,y$, maxima showed $[\;]$ as the otput. I inserted the system of equation through the solve algebraic system option available under the equation option in the status bar of the GUI wxmaxima. So what should I do to get a proper answer as output, please suggest.
