Which inequality is obtained by simplifying \(6x+2y\geq 12\)?

Answer and explanation

Correct answer: \(3x+y\geq 6\)

Dividing both sides of the inequality by the positive number \(2\) gives \(6x/2+2y/2\geq 12/2\), i.e., \(3x+y\geq 6\). The inequality sign does not change when dividing by a positive number. Option B incorrectly reverses the sign. Exam tip: Check whether the number used for multiplication or division is negative; the inequality sign reverses only for a negative number.
