To solve the inequality \( 5 < 12y - 7 \), Kirk needs to follow these steps:
-
Add 7 to both sides: \[ 5 + 7 < 12y \] which simplifies to: \[ 12 < 12y \]
-
Divide both sides by 12: \[ \frac{12}{12} < y \] which simplifies to: \[ 1 < y \]
So the correct explanation of the steps he used to find the solution set of the inequality is:
Kirk adds 7 to both sides of the inequality and then divides both sides of the equivalent inequality by 12 to get \( 1 < y \).
This corresponds to the first response option:
- Kirk adds 7 to both sides of the inequality and then divides both sides of the equivalent inequality by 12 to get \( 1 < y \).
