What is the solution of the inequality \\(x+8>20\\)?

Answer and explanation

Correct answer: \\(x>12\\)

Subtracting 8 from both sides of \\(x+8>20\\) gives \\(x>12\\). The inequality sign does not change when the same number is added to or subtracted from both sides. Option C is incorrect because substituting \\(x=12\\) gives \\(20>20\\), which is false. Exam tip: The inequality sign reverses only when both sides are multiplied or divided by a negative number.
