असमानता \(\frac{2x+3}{5}-\frac{x-4}{2}\le\frac{7-x}{10}\) का हल क्या है?
What is the solution of \(\frac{2x+3}{5}-\frac{x-4}{2}\le\frac{7-x}{10}\)?
Explanation opens after your attempt
A. \(x\ge\frac{7}{2}\)
Concept
Multiplying by positive (10) gives (2(2x+3)-5(x-4)\le7-x). Simplification gives \(26-x\le7-x\), which is false, so no solution exists.
Why this answer is correct
The correct answer is A. \(x\ge\frac{7}{2}\). Multiplying by positive (10) gives (2(2x+3)-5(x-4)\le7-x). Simplification gives \(26-x\le7-x\), which is false, so no solution exists.
Exam Tip
धनात्मक (10) से गुणा करने पर (2(2x+3)-5(x-4)\le7-x) मिलता है। सरलीकरण से \(26-x\le7-x\), जो असत्य है, अतः कोई हल नहीं।
