\( x = -7 \) and \( x = 11 \).
Solución
To solve the equation \( |x - 2| = 9 \), we consider the definition of absolute value, which leads to two possible scenarios:
1. **Positive Case:**
\[
x - 2 = 9 \\
x = 9 + 2 \\
x = 11
\]
2. **Negative Case:**
\[
x - 2 = -9 \\
x = -9 + 2 \\
x = -7
\]
Therefore, the solutions are:
\[
x = -7 \quad \text{(smaller value)}
\]
\[
x = 11 \quad \text{(larger value)}
\]

To solve the equation \( |x-2|=9 \), we need to consider the definition of absolute value. This leads us to two possible equations: 1. \( x - 2 = 9 \) which simplifies to \( x = 11 \) (the larger value). 2. \( x - 2 = -9 \) which simplifies to \( x = -7 \) (the smaller value). Thus, we have \( x=-7 \) (smaller value) and \( x=11 \) (larger value). So, \( x=\square \) (smaller value) is \(-7\) and \( x=\square \) (larger value) is \(11\).
