What is the value of the equilibrium constant for the overall reaction?

Question

​​ AgCl (s) + 2NH3 (aq) Ag(NH3)2+ (aq) + Cl- (aq) Knet = ?

Answer 1

AgCl(s) ==> Ag^+ + Cl^-. Write Ksp for this.
Ag^+ + 2NH3 ==> [Ag(NH3)2]^+ Write Kformation for this one.

Overall is is
AgCl + 2NH3 ==> [Ag(NH3)2]^+ + Cl^-
Wrote Keq expression for this.

Then if you will multiply Ksp*Kformation you will get the overall equilibrium constant for the overall reaction.
