असमानता (5(x-1)+2<5x) का हल समुच्चय क्या है?
What is the solution set of the inequality (5(x-1)+2<5x)?
Explanation opens after your attempt
A. सभी \(x\in\mathbb{R}\)All \(x\in\mathbb{R}\)
Concept
Simplifying gives (5x-3<5x). Subtracting (5x) gives (-3<0), which is true, so all real (x) are solutions.
Why this answer is correct
The correct answer is A. सभी \(x\in\mathbb{R}\) / All \(x\in\mathbb{R}\). Simplifying gives (5x-3<5x). Subtracting (5x) gives (-3<0), which is true, so all real (x) are solutions.
Exam Tip
सरल करने पर (5x-3<5x) मिलता है। (5x) घटाने पर (-3<0) सत्य है इसलिए सभी वास्तविक (x) हल हैं।
