Respuesta:
To simplify the expression \((4x - 5y - 9z) + (-2y + 4z - 2x) + (2z - y + 5x)\), we combine like terms.
Let's group the terms with \(x\), \(y\), and \(z\):
1. **Terms with \(x\)**:
\[
4x - 2x + 5x
\]
2. **Terms with \(y\)**:
\[
-5y - 2y - y
\]
3. **Terms with \(z\)**:
\[
-9z + 4z + 2z
\]
Now, simplify each group:
1. **Combining \(x\) terms**:
\[
4x - 2x + 5x = 7x
\]
2. **Combining \(y\) terms**:
\[
-5y - 2y - y = -8y
\]
3. **Combining \(z\) terms**:
\[
-9z + 4z + 2z = -3z
\]
Putting it all together, the simplified expression is:
\[
7x - 8y - 3z
\]
