What is the correct form in terms of (y) for (x-3y\le9)?असमानता (x-3y\le9) में (y) के रूप में सही रूप कौन सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (y\ge\frac{x-9}{3})(y\ge\frac{x-9}{3})
From (x-3y\le9), we get (-3y\le9-x), hence (y\ge\frac{x-9}{3}). Dividing by a negative reverses the sign.(x-3y\le9) से (-3y\le9-x), इसलिए (y\ge\frac{x-9}{3}) है। ऋणात्मक से भाग देने पर चिन्ह उलटता है।
