What is the common solution of (x+y\leq 6), (x+y\geq 6), (x-y\leq 2), and (x-y\geq 2)?असमानताओं (x+y\leq 6), (x+y\geq 6), (x-y\leq 2), (x-y\geq 2) का संयुक्त हल कौन सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Only the point ((4,2))केवल बिंदु ((4,2))
The first two conditions give (x+y=6), and the next two give (x-y=2). Their intersection is ((4,2)).पहली दो शर्तें (x+y=6) और अगली दो शर्तें (x-y=2) देती हैं। दोनों रेखाओं का प्रतिच्छेद ((4,2)) है।
