To simplify the equation \( 57 = 5y - 13 \), we can solve for \( y \).
- Start by isolating the \( 5y \) term. Add 13 to both sides of the equation:
\[ 57 + 13 = 5y \]
\[ 70 = 5y \]
- Now, divide both sides by 5 to solve for \( y \):
\[ y = \frac{70}{5} \]
\[ y = 14 \]
So, the simplified answer is \( y = 14 \).
