When you find the opposite of a sum or a difference,
you change the sign of each term of the sum or difference.
OpenStudy (skullpatrol):
$$\huge -(a \pm b) = (-a) \pm (-b)$$
OpenStudy (skullpatrol):
$$\huge\text{Recall:}$$
$$\huge -a=-1a$$
$$\huge\text{Let}$$ $$\huge a = 5v-y+6$$
$$\huge\text{then}$$ $$\huge-a = -(5v-y+6)=-1•(5v-y+6)$$
$$\huge\text{since}:$$ $$\huge a(b+c)=ab+ac$$
$$\huge -(5v-y+6)=-1•(5v-y+6)=(-1)5v-(-1)y+(-1)6$$
$$\huge = -5v+y-6$$
