Which is the number line solution of (\frac{4-3x}{5}\le -1)?असमानता (\frac{4-3x}{5}\le -1) का संख्या रेखा पर हल कौन-सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (x\ge 3), closed dot at (3) shaded right(x\ge 3), (3) पर बंद बिंदु और दाईं ओर
(4-3x\le -5) gives (-3x\le -9), so (x\ge 3). In exams, reverse the inequality when dividing by a negative coefficient.(4-3x\le -5) से (-3x\le -9), इसलिए (x\ge 3)। परीक्षा में negative coefficient से divide करते समय inequality reverse करें।
