Transcript text: Solve the following absolute value equation. If needed, write your answer as a fraction reduced to lowest terms.
\[
|6 z-6|=9
\]
Solution
Solution Steps
To solve the absolute value equation \(|6z - 6| = 9\), we need to consider the definition of absolute value. The equation \(|A| = B\) implies two possible equations: \(A = B\) and \(A = -B\). Therefore, we will split the given equation into two separate linear equations and solve each for \(z\).
Solution Approach
Split the absolute value equation into two separate equations:
\(6z - 6 = 9\)
\(6z - 6 = -9\)
Solve each equation for \(z\).
Check if the solutions are valid.
Step 1: Split the Absolute Value Equation
Given the equation \(|6z - 6| = 9\), we split it into two separate linear equations:
\(6z - 6 = 9\)
\(6z - 6 = -9\)
Step 2: Solve Each Equation
Solve the first equation:
\[
6z - 6 = 9
\]
Add 6 to both sides:
\[
6z = 15
\]
Divide by 6:
\[
z = \frac{15}{6} = \frac{5}{2}
\]
Solve the second equation:
\[
6z - 6 = -9
\]
Add 6 to both sides:
\[
6z = -3
\]
Divide by 6:
\[
z = \frac{-3}{6} = \frac{-1}{2}
\]
Final Answer
The solutions to the equation \(|6z - 6| = 9\) are:
\[
\boxed{z = \frac{5}{2} \text{ or } z = \frac{-1}{2}}
\]
