If \(m=n\) and \(p < q\), which of the following must be true?
(A) \(m - p > n - q\)
(B) \(p - m > q - n\)
(C) \(m - p < n - q\)
(D) \(mp > nq\)
(E) \(m + q < n + p\)
Kudos for the right answer and explanation

Given: \(p < q\)
Multiply both sides of the inequality by -1 to get: \(-p > -q\) (since we multiplied both sides of the inequality by NEGATIVE value, we REVERSED the direction of the inequality symbol)
Add \(m\) to both sides to get: \(-p + m> -q + m\)
Since we're told that \(m=n\), we can replace the second \(m\) with \(n\) to get: \(-p + m> -q + n\)
Rearrange the terms to get: \(m-p> n-q\)
Answer: A
Cheers,
Brent
