I want to find the solution for the eqautions x^2+y^2==3*x*y^2, x^3-x^2==y^2-y and plot graphs in matlab.

To solve the equations mathematically, the command [solx,soly]=solve(x^2+y^2==3*x*y^2, x^3-x^2==y^2-y) can be used. However, I am unable to plot a graph for 'solx'. Can you please help with the plotting part of both solx,soly.

syms x y
[solx,soly]=solve(x^2+y^2==3*x*y^2, x^3-x^2==y^2-y)

Thank you for the answer. If we use 'plot(solx,soly,'ok')', the imaginary part of the equations is ignored. How do we plot the imaginary part? What is the plot for 'solx'?
