Which is the solution of the compound inequality (-2<\frac{5-x}{3}\leq 4)?संयुक्त असमानता (-2<\frac{5-x}{3}\leq 4) का हल कौन सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (-7\leq x<11)(-7\leq x<11)
After multiplying by positive (3), we get (-6<5-x\leq 12), then the direction changes because of the negative part. The correct solution is (-7\leq x<11).धनात्मक (3) से गुणा करने के बाद (-6<5-x\leq 12) मिलता है, फिर ऋणात्मक भाग के कारण दिशा बदलती है। सही हल (-7\leq x<11) है।
