y>\frac{\frac{1}{7}}{-3}
Divide both sides by -3. Since -3 is negative, the inequality direction is changed.
y>\frac{1}{7\left(-3\right)}
Express \frac{\frac{1}{7}}{-3} as a single fraction.
y>\frac{1}{-21}
Multiply 7 and -3 to get -21.
y>-\frac{1}{21}
Fraction \frac{1}{-21} can be rewritten as -\frac{1}{21} by extracting the negative sign.
