Solution:
Given the system of equations below
[tex]\begin{gathered} -x^2+3y=20 \\ 3x^2+6y=60 \end{gathered}[/tex]
Using a graphing tool, the graphs of the system of equations is shown below
From the graph above,
The point of intersection of the two graphs is the solution to the system of equation.
Hence, the solution is
[tex](-2,8)\text{ and }(2,8)[/tex]
