What is obtained by writing (x-y\leq 2) in terms of (y)?असमानता (x-y\leq 2) को (y) के रूप में लिखने पर क्या मिलेगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (y\geq x-2)(y\geq x-2)
From (x-y\leq 2), (-y\leq 2-x), so (y\geq x-2). The sign changes when dividing by a negative number.(x-y\leq 2) से (-y\leq 2-x), इसलिए (y\geq x-2) मिलता है। ऋणात्मक से भाग देने पर चिन्ह बदलता है।
