Help moving the x axis of a movieclip

I was wondering if anybody could help me or knows of a tutorial that shows how to move the x axis of a movieclip.

I am almost finished with a site and I have five main buttons at the top- Home - About - Services - Portfolio - Contact. Then I have placed a movieclip in the center of the stage with an image inside that has a width of 3740. This leaves 747 for each section. I need it to move over 747 for each section plus or minus and I know that from Home to Contact it will have to move 2992 but I think I can figure all that out as soon as I just figure out how to get it to move and set a speed.

Thanks in advance.
