$\large\begin{cases} x^2+y+x^3y+xy^2+xy=\frac{-5}{4}\\x^4+y^2+xy(1+2x)=\frac{-5}{4}\end{cases}$ Find the sum of all $$x$$ and $$y$$ from pairs of Real Numbers that satisfy the system of equations above. Round to 2 decimal places.

Note: If the system above has $$(5;2)$$ and $$(0;3)$$ as the only solutions, then the sum of all $$x$$ and $$y$$ is $$5+2+0+3=10$$
