What value of k makes the equation true? k – 26.7 = 12.8 A. 13.9 B. 38.5 C. 39.5 D. 39.9

OpenStudy (knowledge):

You add both sides by 26.7. Since you add both sides by that number, the left side will only have k left because -26.7+26.7 is equal to zero. Then the right side is 12.8+26.7. You add and get your answer.

what does that equal to? 12.8+26.7= 39.5
