To find the number of solutions to the equation \( 9s - 1 = 8 + 8s \), we can start by simplifying it.
First, let’s rearrange the equation to bring like terms together. Subtract \( 8s \) from both sides:
\[ 9s - 8s - 1 = 8 \]
This simplifies to:
\[ s - 1 = 8 \]
Next, add 1 to both sides:
\[ s = 9 \]
Thus, the equation has one solution, which is:
\[ s = 9 \]
Therefore, the answer is that the equation \( 9s - 1 = 8 + 8s \) has 1 solution.
