Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: No solutionकोई हल नहीं
The same quantity (x+y) cannot be at most (4) and at least (7) at the same time. Identify contradictory inequalities first.एक ही राशि (x+y) एक साथ (4) से कम और (7) से अधिक नहीं हो सकती। विरोधी असमानताओं को पहले पहचानें।
