To solve for \( y \) in the equation \( y - 9.49 = 3.51 \), you need to isolate \( y \).
- Add 9.49 to both sides of the equation:
\[ y - 9.49 + 9.49 = 3.51 + 9.49 \]
- This simplifies to:
\[ y = 3.51 + 9.49 \]
- Now, perform the addition:
\[ y = 13.00 \]
Therefore, the solution is:
\[ y = 13.00 \]
