In the first circuit you can assume the voltage at the base is (roughly) fixed and ignore base current, so use KCL to sum the currents at the base, and we get (Vcc - Vbe)/Rb2 = C * d/dt (Vc). In reality the current gain is finite, and Vbe changes with collector current etc. so that equation is only an approximation.
