Answer
\( y > \frac{6}{7} \)
Solution
Solve the equation \( \frac{-7y}{3}-5<-7 \).
Solve the inequality by following steps:
- step0: Solve for \(y\):
\(\frac{-7y}{3}-5<-7\)
- step1: Rewrite the fraction:
\(-\frac{7y}{3}-5<-7\)
- step2: Multiply both sides:
\(\left(-\frac{7y}{3}-5\right)\times 3<-7\times 3\)
- step3: Multiply the terms:
\(-7y-15<-21\)
- step4: Move the constant to the right side:
\(-7y<-21+15\)
- step5: Add the numbers:
\(-7y<-6\)
- step6: Change the signs:
\(7y>6\)
- step7: Divide both sides:
\(\frac{7y}{7}>\frac{6}{7}\)
- step8: Divide the numbers:
\(y>\frac{6}{7}\)
The solution to the inequality \( \frac{-7y}{3}-5<-7 \) is \( y > \frac{6}{7} \).

The Deep Dive
To solve the inequality \( \frac{-7y}{3} - 5 < -7 \), start by isolating the term with \( y \). 1. Add 5 to both sides: \[ \frac{-7y}{3} < -7 + 5 \] \[ \frac{-7y}{3} < -2 \] 2. Multiply both sides by -3/7 (remember to reverse the inequality when multiplying by a negative): \[ y > \frac{-2 \times -3}{7} \] \[ y > \frac{6}{7} \] Thus, the solution to the inequality is \( y > \frac{6}{7} \).
