If (x>3), which statement about (2x-5) is necessarily correct?यदि (x>3) है, तो (2x-5) के लिए कौन सा कथन निश्चित रूप से सही है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (2x-5>1)(2x-5>1)
Multiplying (x>3) by (2) gives (2x>6), and subtracting (5) gives (2x-5>1). Positive multiplication does not reverse the sign.(x>3) को (2) से गुणा कर (2x>6) और (5) घटाकर (2x-5>1) मिलता है। धनात्मक गुणा में चिन्ह नहीं बदलता।
