After solving 2x − 3 ≥ 7, which part will be shaded on the number line?

Answer and explanation

Correct answer: x ≥ 5; a closed dot at 5 and shading to the right

Solve the inequality step by step while preserving the inequality direction. Starting with 2x − 3 ≥ 7, add 3 to both sides to obtain 2x ≥ 10. Dividing by the positive number 2 gives x ≥ 5; the sign does not reverse because the divisor is positive. Since equality is included by ≥, the value 5 belongs to the solution set and must be shown with a closed dot. Values greater than 5 lie to the right, so that side is shaded. Therefore option A is correct. An open dot would represent a strict inequality, and shading left would represent x ≤ 5 or x < 5.
