Question

Which equation demonstrates the opposite of a sum property? A. (22 + 10) + 3 = (10 + 22) + 3 B. –5 + 13 = 13 + (–5) C. (12 + (–4)) + 14 = 12 + ((–4) + 14) D. –(–6 + 17) = 6 + (–17)

Answer 1

For all real numbers a and b,
-(a+b)=(-a)+(-b)
The opposite of a sum of real numbers is equal to the sum of the opposites

D.
–(–6 + 17) = 6 + (–17)
