To solve the inequality \( 5 < 12y - 7 \), Kirk would follow these steps:
-
Add 7 to both sides of the inequality:
\( 5 + 7 < 12y - 7 + 7 \)
\( 12 < 12y \) -
Divide both sides by 12 (since 12 is positive, the inequality direction remains the same):
\( \frac{12}{12} < y \)
\( 1 < y \)
or equivalently, \( y > 1 \).
From this reasoning, the correct statement that explains Kirk's steps is:
"Kirk adds 7 to both sides of the inequality and then divides both sides of the equivalent inequality by 12 to get \( 1 < y \)."
