At least in this case, just use Simplify.
Solve[Rr/s == Rr + x, x][[1]] // Simplify
{x -> Rr*(1/s - 1)}

Dear Group-
How can one get rid of the minus sign in:
In:
Factor[Solve[Rr/s == Rr + x, x]]
Out:
{{x -> -((Rr (-1 + s))/s)}}
We'd like Mathematica to provide answers with the minus sign
"multiplied through" (remove Factor[] doesn't solve the problem)
Thank you in advance all.
