using System;
class Solution
{
   static void Main(string[] args)
   {
     string[] input = Console.ReadLine().Split(' ');
     int a = int.Parse(input[0]);
     int b = int.Parse(input[1]);
     int c = int.Parse(input[2]);
     
     if(a == b && b == c)
     {
       if(a + b > c)
       	Console.WriteLine("Yes");
       else
         Console.WriteLine("No");
     }
     else
       Console.WriteLine("No");
   }
