असमानता \(2-\frac{5x-1}{4}<\frac{x+7}{2}\) का हल समुच्चय क्या है?
What is the solution set of \(2-\frac{5x-1}{4}<\frac{x+7}{2}\)?
Explanation opens after your attempt
A. \(x>-\frac{5}{7}\)
Concept
Multiplying by (4) gives (8-(5x-1)<2x+14). Thus (9-5x<2x+14), so \(x>-\frac{5}{7}\).
Why this answer is correct
The correct answer is A. \(x>-\frac{5}{7}\). Multiplying by (4) gives (8-(5x-1)<2x+14). Thus (9-5x<2x+14), so \(x>-\frac{5}{7}\).
Exam Tip
(4) से गुणा करने पर (8-(5x-1)<2x+14) मिलता है। इससे (9-5x<2x+14), इसलिए \(x>-\frac{5}{7}\)।
