In Skyrim:
To enchant you need:
1. Find an Arcane Enchanter (i.e. the one in Forengor's office)
2. Disenchant the enchanted item (if you don't know any enchantments)
3. Select your soul gem
4. Select the enchantment
5. Press X, Square, or E (I guess)
NOTE: A good way to get an enchanted item would be after you retrieve the Dragonstone, Jarl Balgruf will give you an enchanted battleaxe.
