how to use maple solve with undirect input of system of equation? - Messages

Hi,
I am pretty new to smath and I have some trouble with the maple plugin trying to solve a simple system of equation.
If I input the system of equation directly in the maple(solve(sys{}, var{})), I have no trouble solving the system of equation.
Elsewhere if I define the system of equation outside the maple(solve(...)), e.g. s=sys{...}, and then call it by name in the maple(solve(s, ...)), then I get no solution.
What I am missing?
I attach a minimal working example
maple_solve_system.sm

Unfortunately, maple function can only work with arguments given directly. Your case requires an expression translation operation, which is difficult to implement in the general case. This function is recommended for simple symbolic operations.

I will be back later. You can explicit RootOf

Thanks for clarification.
Is there another method or plugin recommended to solve symbolically a system of equation?
I kinda stumbled upon maple searching trough the forum, but also found reference to the maxima plugin. I am not sure which is the best case and gravitated toward maple because it didn't require further installation aside from the plugin itself.

Explicit the Triplet [R1, R2, R3]

kompre,
You can use the Solve command of the maxima plugin. maxima_Solve_system.sm
P.S. I believe that Jean's solution is not correct because the solutions are not ordered

Thank you!
This seems to be exactly what I was looking for
(I try to use the thank button, but get an error, so accept non statistical gratitude :d )
