What is the easiest way to remove old wallpaper?

i removed the wall border, i used a wet rag and a spatula to scrap the adhesive off, but one spot on the wall they didnt have enough wallpaper to cover the wall. so now i have ugly wallpaper and one spot that is white where the wall was painted. someone said to use steam. where do i get a steam machine or what is another method? my husband is off this weekend so i have a helper LOL I need help I am kind of clueless!! i have checked other spots and i believe the whole wall is painted white underneath.
