[sympy] Re: issue solving algebraic system of equations

With the multiplication, after a few minutes, the answer I get is: [(0, 0, 0), (0, 1, 0), (0, RZZ/RYZ, (RYZ*RZYI - sqrt(RYZ**2*RZYI**2 + 4*RYZ**2*RZYII - 4*RYZ*RZYII*RZZ))/(2* RYZ*RZYII)), (0, RZZ/RYZ, (RYZ*RZYI + sqrt(RYZ**2*RZYI**2 + 4*RYZ**2*RZYII - 4*RYZ*RZYII*RZZ))/(2* RYZ*RZYII)),

Hi, please have a look at the following code: from sympy import * X,Y,Z = symbols("\X,\Y,\Z") Rxy,Rxz, Ry,Ryx,Ryz, Rz,Rzy,Rzz = symbols("\\RXY,\\RXZ, \\RY,\\RYX,\\RYZ, \\RZ,\\RZY,\\RZZ") Rzy1,Rzy2 = symbols("\\RZYI,\\RZYII") dimensionless_DES_list = [X*(1-X - Ryx*Y),
