What is the correct solution interval of the double inequality ( -2<\frac{5-3x}{4}\leq 1 )?दोहरी असमानता ( -2<\frac{5-3x}{4}\leq 1 ) का सही हल-अंतराल क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ( \frac{1}{3}\leq x<\frac{13}{3} )( \frac{1}{3}\leq x<\frac{13}{3} )
Dividing by (-3) reverses both inequality signs. Hence the solution is ( \frac{1}{3}\leq x<\frac{13}{3} ).(-3) से भाग देने पर दोनों असमानता-चिह्न उलटते हैं। इसलिए हल ( \frac{1}{3}\leq x<\frac{13}{3} ) है।
