The image contains two algebraic expressions that need to be simplified by combining like terms.

The expressions are:

1. $-5 - 3 - 4 + 3x + 5y$
2. $-8 + 4 + 3x + 5y$

Steps to simplify:

1. Group the like terms from both expressions:

   • Combine constants: $(-5 - 3 - 4)$ and $(-8 + 4)$
   • Combine the terms with $x$: $(+3x + 3x)$
   • Combine the terms with $y$: $(+5y + 5y)$

2. Simplify each group:

   • Constants: $-5 - 3 - 4 = -12$ and $-8 + 4 = -4$
   • $x$-terms: $3x + 3x = 6x$
   • $y$-terms: $5y + 5y = 10y$

3. Result after combining: $-12 - 4 + 6x + 10y$

4. Final simplified result: $-16 + 6x + 10y$

The simplified expression is: $\boxed{-16 + 6x + 10y}$.
