द्वि-असमीका \(-2\le \frac{5x-1}{4}<3\) का समाधान समुच्चय चुनिए।
Choose the solution set of \(-2\le \frac{5x-1}{4}<3\).
Explanation opens after your attempt
Correct Answer
D. \(-\frac{7}{5}\le x<\frac{13}{5}\)
Concept
\(-8\le 5x-1<12\) gives \(-7\le 5x<13\), so \(-\frac{7}{5}\le x<\frac{13}{5}\). Preserve boundary signs at every step.
Why this answer is correct
The correct answer is D. \(-\frac{7}{5}\le x<\frac{13}{5}\). \(-8\le 5x-1<12\) gives \(-7\le 5x<13\), so \(-\frac{7}{5}\le x<\frac{13}{5}\). Preserve boundary signs at every step.
Exam Tip
\(-8\le 5x-1<12\) से \(-7\le 5x<13\), इसलिए \(-\frac{7}{5}\le x<\frac{13}{5}\)। परीक्षा में हर चरण में सीमा चिन्ह बनाए रखें।
