Which is the solution of (-5\leq \frac{x-1}{2}<4)?असमानता (-5\leq \frac{x-1}{2}<4) का हल कौन सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (-11\leq x<9)(-11\leq x<9)
Multiplying by (2) gives (-10\leq x-1<8). Adding (1) gives (-9\leq x<9), so check endpoints carefully.(2) से गुणा करने पर (-10\leq x-1<8) मिलता है। फिर (1) जोड़कर (-9\leq x<9) नहीं, सही (-9\leq x<9) होगा।
