Solve for x . 12−x/9=11 (1 point) x=

1 answer

To solve for \( x \) in the equation

\[ \frac{12 - x}{9} = 11, \]

first, multiply both sides by 9 to eliminate the fraction:

\[ 12 - x = 11 \times 9. \]

Calculating the right side:

\[ 11 \times 9 = 99, \]

so the equation simplifies to:

\[ 12 - x = 99. \]

Next, subtract 12 from both sides:

\[ -x = 99 - 12, \]

which simplifies to:

\[ -x = 87. \]

Now, multiply both sides by -1 to solve for \( x \):

\[ x = -87. \]

Thus, the solution is

\[ \boxed{-87}. \]
