Bot GPT 4-o mini To solve the equation \( 8x - 9 = 5x + 9 \), follow these steps:
1. **Isolate the variable on one side**: Start by getting all terms containing \( x \) on one side and constant terms on the other side.
\[
8x - 5x = 9 + 9
\]
Simplifying both sides gives:
\[
3x = 18
\]
2. **Solve for \( x \)**: Divide both sides by 3.
\[
x = \frac{18}{3} = 6
\]
So, the solution to the equation \( 8x - 9 = 5x + 9 \) is:
\[
\boxed{6}
\]
