State the solution of (9-x\le 5).असमानता (9-x\le 5) का हल बताइए।
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (x\ge 4)(x\ge 4)
(9-x\le 5) gives (-x\le -4), and dividing by (-1) gives (x\ge 4). Reverse the sign when dividing by a negative number.(9-x\le 5) से (-x\le -4) मिलता है और (-1) से भाग देने पर (x\ge 4) है। ऋणात्मक से भाग देने पर चिन्ह उलटें।
