Which is the correct solution of \(7-x\ge 2\)?
A. \(x\le 5\)
\(7-x\ge 2\) से \(-x\ge -5\) मिलता है और ऋणात्मक से भाग देने पर \(x\le 5\)। (-x) हटाते समय चिह्न पलटें। / From \(7-x\ge 2\), we get \(-x\ge -5\), and dividing by a negative gives \(x\le 5\). Reverse the sign when removing (-x).

What is the solution of the inequality \(6x-5\ge 19\)?
A. \(x\ge 4\)
पहले दोनों ओर (5) जोड़ें तो \(6x\ge 24\) मिलता है फिर (6) से भाग दें। धनात्मक भाग में चिह्न नहीं बदलता। / First add (5) to both sides to get \(6x\ge 24\), then divide by (6). Division by a positive number does not change the sign.
