[?] Solve the following equation?

Questions
1

Consider the following code:

TC = L + (1 - q) + SC + Ca + 
      Cr + (Exp[1 - RealAbs[1 - \[Mu]/Subscript[y, 0]]])*
       MC + ((Exp[(Subscript[\[Sigma], 1] - \[Sigma])/(
           Subscript[\[Sigma], 1] - Subscript[\[Sigma], 2])]) - 1)*DC

n = D[TC, {{\[Sigma], \[Mu]}}]

Solve[n == 0 // Rationalize, {\[Sigma], \[Mu]}]

I need to solve the equation, but running so long.

TC = L + (1 - q) + SC + Ca + Cr + (Exp[1 - RealAbs[1 - ?/y0]])*
MC + ((Exp[(?1 - ?)/(?1 - ?2)]) - 1)*DC

n = D[TC, {{?, ?}}] // FullSimplify

Solve[{n[[1]] == 0, n[[2]] == 0}, {?, ?}]

(*{}*)

Solve find no solutions.

Thanks, I’ll take a look and get back to you. Will be very interested to see what others come back with (if they’re giving it a go).
