If I want to know the effect of the moderator variable on the relationship between the mediator and independent, and the effect of this on a dependent.What are the necessary regression equations for this?.
Dear Eman Magdy
Since you have mediate and moderate variables, it is useful to read this paper which conducted by
Amanda J. Fairchildcorresponding author and David P. MacKinnon
A General Model for Testing Mediation and Moderation Effects

Try to use path analysis and it's easy to describe direct and indirect effects then.
