What is the solution of ( -1\leq \frac{x+3}{2}<5 )?असमानता ( -1\leq \frac{x+3}{2}<5 ) का हल क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ( -5\leq x<7 )( -5\leq x<7 )
Multiplying by positive (2) gives (-2\leq x+3<10), then subtracting (3) gives (-5\leq x<7). Positive multiplication does not change direction.धनात्मक (2) से गुणा करने पर (-2\leq x+3<10) और (3) घटाने पर (-5\leq x<7) मिलता है। धनात्मक गुणन में दिशा नहीं बदलती।
