Equipped creature gets +1/+0 for each Equipment attached to it.
Equip {2} ({2}: Attach to target creature you control. Equip only as a sorcery. This card enters the battlefield unattached and stays on the battlefield if the creature leaves.)
Golem-Skin Gauntlets is counted by its own ability, so it gives at least +1/+0.
The bonus from Golem-Skin Gauntlets is in addition to whatever bonus the other Equipment gives it.
