Change the right side of −3(y+7) ≠−3y+21- 3 ( y + 7 ) \neq - 3 y + 213(y+7) =3y+21 so both sides of the equation are equal.

A) −3(y+7) =3y+21- 3 ( y + 7 ) = 3 y + 213(y+7) =3y+21
B) −3(y+7) =−3y+7- 3 ( y + 7 ) = - 3 y + 73(y+7) =3y+7
C) −3(y+7) =−3y−21- 3 ( y + 7 ) = - 3 y - 213(y+7) =3y21
D) −3(y+7) =−3y+3- 3 ( y + 7 ) = - 3 y + 33(y+7) =3y+3
E) −3(y+7) =3+21y- 3 ( y + 7 ) = 3 + 21 y3(y+7) =3+21y

Final Answer :
C
Explanation :
Distributing −3-33 across (y+7)(y + 7)(y+7) gives −3y−21-3y - 213y21 , making option C correct.
