Hi
W10 SageMath 9.2
why I m not allowed to have only one equation in the equation list, (uncomment line 4)?
varL=var('a,b,c,d',domain='real')
eqL=[a == -d, b*c == 0, a*(b + c) == 0]
eqL=[a == -d, b*c == 0]
#eqL=[a == -d]
show("so we need : \t ",eqL)
S=solve(eqL,varL)
show(S)
but with eqL=[a == -d,1==1] ,solve is ok
