1 answer

To solve the inequality \( 5 < 12y - 7 \), Kirk follows these steps:

  1. Add 7 to both sides: This step will help isolate the term involving \( y \). \[ 5 + 7 < 12y \implies 12 < 12y \]

  2. Divide both sides by 12: This step will solve for \( y \). Note that when dividing by a positive number, the inequality symbol does not change direction. \[ \frac{12}{12} < y \implies 1 < y \]

In conclusion, the correct statement that explains the steps is:

Kirk adds 7 to both sides of the inequality and then divides both sides of the equivalent inequality by 12 to get \( 1 < y \).
