how can i change my back wheel on peugot speedfight2 moped??

Take off the exhaust, this exposes the rear wheel. Loosen the big nut in the center of the wheel (might be a plastic cover hiding it), you may also need an impact rachet. If you don't have one then get a mate to sit on the bike OFF the mainstand & pull in the brakes.
Now using a size 22 socket (could be a different size) slacken off the big nut. Prop the scoot back up on the mainstand, if it has a drum brake then loosen the brake cable at the wheel. If it has a disc then take off the caliber where it's mounted onto the transmission, do not take off the hose pipe.
Now wriggle the wheel towards you, it should now be able to slide off the driveshaft. Do the reverse when assembling it & don't forget to tighten up your brakes.
