To solve the equation \( 9x = 99 \) using the multiplication property, we'll first isolate \( x \).
- Divide both sides of the equation by 9:
\[ x = \frac{99}{9} \]
- Now, perform the division:
\[ x = 11 \]
So, the solution is \( x = 11 \).
Check:
To verify the solution, substitute \( x \) back into the original equation:
\[ 9x = 99 \]
Substituting \( x = 11 \):
\[ 9(11) = 99 \]
Calculating the left side:
\[ 99 = 99 \]
The left side equals the right side, confirming that our solution is correct.
Thus, the solution is:
\[ \text{The solution is } x = 11. \]
