Can some one please tell me how are we finding solutions, for example when x = 3 how is number of solutions of y + z is 20. Three variables x,y,z have sum of 30. All three of them are non-negative integers. If any two variables don't have same value and exactly one variable has a value less than or equal to three, then find the number of possible solution for variables.
