Which value of k makes 5-k+12=16 a true statement? Choose 1 answer: (A) k=1 (B) k=2 (C) k=3 (D) k=4

Combine like terms: Combine like terms on the left side of the equation. 5 + 12 = 17, so the equation becomes 17 - k = 16.Isolate variable: To find the value of k, we need to isolate k on one side of the equation. We can do this by subtracting 17 from both sides of the equation. 17 - k - 17 = 16 - 17 This simplifies to -k = -1.Solve for k: To solve for k, we need to get rid of the negative sign in front of k. We can do this by multiplying both sides of the equation by -1. -k * -1 = -1 * -1 This simplifies to k = 1.
