The value of the expression \(\frac{x + 3y}{5 + 5y}\) when \(x = -2\) and \(y = 4\) is \(0.4\).

Would you like more details on the steps? Here are some related questions to consider:

1. What happens if both \(x\) and \(y\) are negative?
2. How would the result change if \(y = 0\)?
3. Can you simplify the expression before substituting values?
4. What if the denominator was quadratic in terms of \(y\)?
5. How can this be expressed as a fraction instead of a decimal?

**Tip:** Always simplify the expression as much as possible before substituting values to avoid calculation errors.
