Which form is correct after simplifying \(-2x-y\le -6\)?
Explanation opens after your attempt
D. \(2x+y\ge 6\)
Concept
Multiplying the whole inequality by (-1) reverses the sign. Hence \(2x+y\ge 6\) is obtained.
Why this answer is correct
The correct answer is D. \(2x+y\ge 6\). Multiplying the whole inequality by (-1) reverses the sign. Hence \(2x+y\ge 6\) is obtained.
