Updates, insertions and deletions are generally a much easier problem than doing queries (essentially a find operation).
If you are referring to generic collections rather than databases, you make a method call like Insert or Add to add an item, and Delete or Remove to remove an item. To change an item, generally you just manipulate the item directly.

Linq targets two interfaces, IEnumerable<T> and IQueryable<T>.
Think about how a delete operation would be performed against an IEnumerable<T>.
How do you delete things from Enumerable.Range(0, 5) ?
