What is the solution of the inequality \\(9-3x<0\\)?

Answer and explanation

Correct answer: \\(x>3\\)

From \\(9-3x<0\\), we get \\(-3x<-9\\). Dividing both sides by \\(-3\\) reverses the inequality sign, giving \\(x>3\\). Option B results from forgetting this sign reversal, while the options with equality incorrectly include \\(x=3\\), which does not satisfy the original strict inequality. Exam tip: Reverse the inequality sign whenever you multiply or divide by a negative number.
