Sort a list of lists by minimum value

I am trying to sort the lists inside a list by their minimum integer value. This is where I am at so far.

var SortedList = from lists in List 
                 orderby lists.List.Min(Min=>Min.value) 
                 ascending
                 select list ;

For example:

var x = new List<int>{ 5, 10, 4, 3, 0 };
var y = new List<int> { 4, -1, -5, 3, 2 };
var z = new List<int> { 3, 1, 0, -2, 2 };

var ListofLists = new List<List<int>> {x, y, z};

The output of my Linq shall be, to sort the lists by the minimum value in the list of lists. The sequence for the Lists in my example would be:

y -> z -> x

I have tried a lot of linq expressions and searched through the web. The question seems to be very simple... Thanks for any kind of help!

It's as easy as:

var sorted = ListofLists.OrderBy(l => l.Min());

Or, if you prefer query syntax, you should do: 

var sorted = from list in ListofLists 
             orderby list.Min()
             select list;
