Answer 1

To solve the equation \( 12 - \frac{x}{9} = 11 \), we can follow these steps:

1. Isolate the term with \( x \): Subtract 12 from both sides: \[ -\frac{x}{9} = 11 - 12 \] \[ -\frac{x}{9} = -1 \]

2. Multiply both sides by -1: \[ \frac{x}{9} = 1 \]

3. Multiply both sides by 9 to solve for \( x \): \[ x = 9 \]

The solution is: \[ \boxed{9} \]
