कौन सा कथन \(2x+5\leq 2x+9\) के लिए सही है?
Which statement is correct for \(2x+5\leq 2x+9\)?
Explanation opens after your attempt
A. सभी \(x\in \mathbb{R}\) हल हैंAll \(x\in \mathbb{R}\) are solutions
Concept
Removing (2x) gives \(5\leq 9\), which is always true. If the variable cancels, check the remaining numerical inequality.
Why this answer is correct
The correct answer is A. सभी \(x\in \mathbb{R}\) हल हैं / All \(x\in \mathbb{R}\) are solutions. Removing (2x) gives \(5\leq 9\), which is always true. If the variable cancels, check the remaining numerical inequality.
Exam Tip
(2x) हटाने पर \(5\leq 9\) मिलता है जो हमेशा सत्य है। चर हट जाए तो बची संख्या असमानता देखें।
