After :
```
from sympy import symbols, solve
f, q, r, h, i, g = map(symbols, 'fqrhig')
e1 = -4*f**2*q - 5*f**2*r - 5*f*r + 4*q**2 + 3*q*r
e2 = -4*f**2*h*q - 4*f**2*i*q - 8*f*g*q - 10*f*g*r - 8*f*h*q - 20*f*h*r -
10*f*i*r + 8*f*q**2/5 - 5*g*r + 4*h*q**2 - 5*h*r + 4*i*q**2 + 4*q**2/5 +
10*q*r + 5*r**2
```
trying `solve([e1, e2], [f, g])` never returns.
FWIW, in Sage, with equivalent definitions :
