What is the solution set of the inequality \(3(x-1)>x+5\)?

Answer and explanation

Correct answer: \(x>4\)

Expanding the bracket gives \(3x-3>x+5\). Subtracting \(x\) from both sides and adding 3 gives \(2x>8\). Dividing by 2 yields \(x>4\), so option A is correct. Option C is incorrect because the strict inequality does not include the boundary value \(x=4\). Exam tip: For \(>\) or \(<\), the boundary point is not included in the solution set.
