Change the right side of $- 3 ( y + 7 ) \neq - 3 y + 21$ so both sides of the equation are equal.
A) $- 3 ( y + 7 ) = 3 y + 21$
B) $- 3 ( y + 7 ) = - 3 y + 7$
C) $- 3 ( y + 7 ) = - 3 y - 21$
D) $- 3 ( y + 7 ) = - 3 y + 3$
E) $- 3 ( y + 7 ) = 3 + 21 y$

Question

Quizplus · Accepted Answer

Distributing $-3$ across $(y + 7)$ gives $-3y - 21$, making option C correct.

Change the Right Side Of −3(y+7)≠−3y+21- 3 ( y + 7 ) \neq - 3 y + 21−3(y+7)=−3y+21
