Suppose a flame of a gas burner stove emits light just like a blackbody.The flame appears blue,emiting most of the light as a wave length of 475 nanometers. what is the temperature of the flame. How do I solve this?

You cannot get the flame temperature from that observation. You do not have blackbody continuum emission, which would be required to get a temperature from the spectrum. The wavelengths that you observe depends upon the emitting species, which happen to be trace amounts of C2 and CN.
T = 3 x 10^6 / wavelength
