Solve the inequality \\(13-3x\leq 4\\).

Answer and explanation

Correct answer: \(x\geq 3\)

Subtracting 13 from both sides gives \\(-3x\leq -9\\). Dividing by \\(-3\\) reverses the inequality sign, so \\(x\geq 3\\). Option A is incorrect because it does not reverse the sign after division by a negative number. Exam tip: Always reverse an inequality sign when multiplying or dividing both sides by a negative number.
