To simplify the expression \( 310x + 16y + 310x + 36y \), we can combine like terms.
First, let's combine the \( x \) terms:
\[ 310x + 310x = 620x \]
Next, we combine the \( y \) terms:
\[ 16y + 36y = 52y \]
Now, we can write the simplified expression:
\[ 620x + 52y \]
So, the simplified expression is \( 620x + 52y \).
