Question

what value of x is a solution to this equation?
9(x - 12) = -9
x = 11
x = 12

Explanation:

Step1: Divide both sides by 9

To isolate the term with \( x \), we divide both sides of the equation \( 9(x - 12)=-9 \) by 9.
\[
\frac{9(x - 12)}{9}=\frac{-9}{9}
\]
Simplifying both sides, we get \( x - 12=-1 \).

Step2: Solve for \( x \)

To solve for \( x \), we add 12 to both sides of the equation \( x - 12=-1 \).
\[
x-12 + 12=-1 + 12
\]
Simplifying both sides, we find \( x = 11 \).

Answer:

\( x = 11 \) (the option "x = 11")
