असमानता (4x+1<4x+9) का हल कौन सा है?
What is the solution of (4x+1<4x+9)?
Explanation opens after your attempt
Correct Answer
A. सभी \(x\in\mathbb{R}\)all \(x\in\mathbb{R}\)
Concept
Subtracting (4x) from both sides gives (1<9), which is always true. When the variable cancels, decide the solution from the truth of the remaining statement.
Why this answer is correct
The correct answer is A. सभी \(x\in\mathbb{R}\) / all \(x\in\mathbb{R}\). Subtracting (4x) from both sides gives (1<9), which is always true. When the variable cancels, decide the solution from the truth of the remaining statement.
Exam Tip
दोनों पक्षों से (4x) घटाने पर (1<9) मिलता है, जो हमेशा सत्य है। चर हटने पर शेष कथन की सत्यता से हल तय करें।
