What is the missing reason in the proof?
Prove –(–y – x) – x = y
Statements Reasons
–(y –x) – x = y + x – x Opposite of a sum property
y + x – x = y + x + (–x) ________________________
y + x + (–x) = y + [x + (–x)] Associative Property of Addition
y + [x + (–x)] = y + 0 Additive Inverse Property
y + 0 = y Additive Identity Property
A.
Definition of Subtraction
B.
