# solve linear system in GF(7)

hi i would like to solve a small linear system in GF(7) whats the syntax ?

```
var('A0','A1','B0','B1','B2','B3')
eqns =
[-A0 + 5*A1 + B0 + 2*B1 + 4*B2 + B3 + 3 == 0,
-3*A0 + 2*A1 + B0 + 4*B1 + 2*B2 + B3 + 1 == 0,
-6*A0 + 6*A1 + B0 + 6*B1 + B2 + 6*B3 - 6 == 0,
-5*A0 + 2*A1 + B0 + B1 + B2 + B3 - 5 == 0,
-4*A0 + 2*A1 + B0 + 3*B1 + 2*B2 + 6*B3 + 6 == 0,
-2*A0 + 4*A1 + B0 + 5*B1 + 4*B2 + 6*B3 + 6 == 0]
```

`solve(eqns,A0,A1,B0,B1,B2,B3)`

will do it in Q or R by default.

thank you
