Kirk solves the inequality 5<12y−7 . Which statement explains the steps he uses to find the solution set of the inequality?(1 point)

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

Kirk adds 7 to both sides of the inequality and then multiplies both sides of the equivalent inequality by 12 to get 144<y.

Kirk adds −7 to both sides of the inequality and then divides both sides of the equivalent inequality by 12 to get (−16)<y.
Kirk adds negative 7 to both sides of the inequality and then divides both sides of the equivalent inequality by 12 to get left parenthesis negative Start Fraction 1 over 6 End Fraction right parenthesis less than y .

Kirk adds 7 to both sides of the inequality, then divides both sides of the equivalent inequality by 12 and reverses the inequality symbol to get 1>y.

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

  1. Add \( 7 \) to both sides of the inequality: \[ 5 + 7 < 12y - 7 + 7 \] This simplifies to: \[ 12 < 12y \]

  2. Divide both sides by \( 12 \): \[ \frac{12}{12} < \frac{12y}{12} \] This simplifies to: \[ 1 < y \]

So, the correct statement that explains the steps he uses 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."
