To solve the inequality \(-3y > 21\), we first divide both sides by \(-3\). However, remember that when you divide or multiply both sides of an inequality by a negative number, you must flip the inequality sign.
So, we have:
\[
y < \frac{21}{-3}
\]
This simplifies to:
\[
y < -7
\]
Therefore, the correct response is:
**y < −7** (y less than negative 7).
So, we have:
\[
y < \frac{21}{-3}
\]
This simplifies to:
\[
y < -7
\]
Therefore, the correct response is:
**y < −7** (y less than negative 7).
