To solve the inequality \(-3y > 21\), we need to isolate \(y\).
1. First, divide both sides of the inequality by -3. Remember that when you divide by a negative number, the direction of the inequality sign reverses:
\[
y < \frac{21}{-3}
\]
2. Simplifying the right side:
\[
y < -7
\]
Thus, the correct answer is:
**y < −7** (y less than negative 7).
