Answer
\( 8x + 7 \)
Solution
To simplify the expression \( 3x + 9y + 5x + 7 - 9y \), follow these steps:
1. **Combine like terms for \( x \):**
\[
3x + 5x = 8x
\]
2. **Combine like terms for \( y \):**
\[
9y - 9y = 0
\]
(These terms cancel each other out.)
3. **Add the constant term:**
\[
7
\]
Putting it all together, the simplified expression is:
\[
8x + 7
\]
**Final Answer:** \( 8x + 7 \)

To simplify the expression \( 3x + 9y + 5x + 7 - 9y \), we start by combining like terms. First, group the \(x\) terms together: \( 3x + 5x = 8x \). Next, group the \(y\) terms: \( 9y - 9y = 0 \). Now, combine the constant term: The \(7\) remains as it is. Putting it all together, the simplified expression is: \[ 8x + 7 \].
