To solve the equation \( 5 - 3(x + 3) = 11 - 8x \), we can outline the steps as follows:
1. **Distribute**: Apply the distributive property to expand the left side of the equation.
\[
5 - 3(x + 3) \rightarrow 5 - 3x - 9
\]
2. **Combine like terms**: Simplify the left side by combining the constants.
\[
5 - 9 = -4 \quad \Rightarrow \quad -3x - 4
\]
This gives us:
\[
-3x - 4 = 11 - 8x
\]
3. **Rearrange terms**: Move all terms involving \( x \) to one side and constants to the other side. Add \( 8x \) to both sides.
\[
-3x + 8x - 4 = 11 \quad \Rightarrow \quad 5x - 4 = 11
\]
4. **Isolate the variable**: Add \( 4 \) to both sides to isolate the \( 5x \).
\[
5x = 11 + 4 \quad \Rightarrow \quad 5x = 15
\]
5. **Solve for \( x \)**: Divide both sides by \( 5 \) to find the value of \( x \).
\[
x = \frac{15}{5} \quad \Rightarrow \quad x = 3
\]
Thus, the steps taken to solve the equation \( 5 - 3(x + 3) = 11 - 8x \) result in \( x = 3 \).
