(1) k – 2 = m + k (2) k = n + 2

(1) k – 2 = m + k => m= -2 Sufficient

(2) k = n + 2 n- n-2 = m => m = -2 Sufficient

Answer D

Target question:What is the value of m?

Given: n – k = m

Statement 1: k – 2 = m + k Subtract k from both sides to get: -2 = m DONE! Since we can answer the target question with certainty, statement 1 is SUFFICIENT

Statement 2: k = n + 2 Subtract 2 from both sides to get: k - 2 = n Subtract k from both sides to get: -2 = n - k Since it's given that n – k = m, we can take the equation -2 = n - k and REPLACE n - k with m When we do this, we get: -2 = m DONE! Since we can answer the target question with certainty, statement 2 is SUFFICIENT
