Answer:

Step 2.

Step-by-step explanation:

Jamie tried to solve the equation.


(2)/(5)n+7=12

Step 1: Subtract 7 from both sides:


\begin{gathered} (2)/(5)n+7-7=12-7 \\ (2)/(5)n=5 \end{gathered}

Jamie's Step 1 was correct.

Step 2: Multiply both sides by 5


\begin{gathered} (2)/(5)n*5=5*5 \\ 2n=25 \\ n=(25)/(2) \end{gathered}

Observe that this is different from what Jamie has. Therefore, Jamie's mistake was in Step 2.
