What will be the solution of x/6 − 1 ≥ 2?

Answer and explanation

Correct answer: x ≥ 18

The governing concept is solving a linear inequality while preserving its direction. Start with x/6 − 1 ≥ 2. Add 1 to both sides, giving x/6 ≥ 3. Multiply both sides by 6. Because 6 is positive, the inequality sign remains unchanged: x ≥ 18. Thus every real number greater than or equal to 18 satisfies the original inequality, and 18 itself is included because the symbol is ≥. Option C is correct. Option A and option D reverse the direction incorrectly, while option B excludes 18 and uses a strict inequality. A sign reversal would be required only if we multiplied or divided by a negative number, which does not happen here. On a number line, the answer is shown by a closed point at 18 with shading to the right.
