What is the solution of the inequality 2(x + 7) ≤ 4x + 6?

Answer and explanation

Correct answer: x ≥ 4

The governing concept is solving a linear inequality while preserving its direction. First distribute 2: 2x + 14 ≤ 4x + 6. Subtract 2x from both sides to obtain 14 ≤ 2x + 6, and then subtract 6 to get 8 ≤ 2x. Dividing by the positive number 2 does not reverse the inequality, so 4 ≤ x, which is conventionally written as x ≥ 4. Therefore option A is correct. Option B reverses the solution direction, while options C and D incorrectly replace the inclusive symbol with a strict one. The endpoint x = 4 must be included because substitution gives equality: 2(11) = 22 and 4(4) + 6 = 22.
