दोहरी असमानता \( -2<\frac{5-3x}{4}\leq 1 \) का सही हल-अंतराल क्या है?
What is the correct solution interval of the double inequality \( -2<\frac{5-3x}{4}\leq 1 \)?
Explanation opens after your attempt
Correct Answer
C. \( \frac{1}{3}\leq x<\frac{13}{3} \)
Concept
Dividing by (-3) reverses both inequality signs. Hence the solution is \( \frac{1}{3}\leq x<\frac{13}{3} \).
Why this answer is correct
The correct answer is C. \( \frac{1}{3}\leq x<\frac{13}{3} \). Dividing by (-3) reverses both inequality signs. Hence the solution is \( \frac{1}{3}\leq x<\frac{13}{3} \).
Exam Tip
(-3) से भाग देने पर दोनों असमानता-चिह्न उलटते हैं। इसलिए हल \( \frac{1}{3}\leq x<\frac{13}{3} \) है।
