We are given the equation:

$\frac{\left| y - 10 \right|}{-2} = -6$

Step 1: Eliminate the denominator by multiplying both sides by -2.

$\left| y - 10 \right| = (-6)(-2)$

$\left| y - 10 \right| = 12$

Step 2: Set up two equations based on the absolute value definition.

The absolute value equation $\left| y - 10 \right| = 12$ gives us two possibilities:

1. $y - 10 = 12$
2. $y - 10 = -12$

Step 3: Solve both equations.

For the first equation: $y - 10 = 12$ $y = 12 + 10$ $y = 22$

For the second equation: $y - 10 = -12$ $y = -12 + 10$ $y = -2$

Step 4: Check for extraneous solutions.

We must substitute both solutions into the original equation to verify.

Checking $y = 22$:

$\frac{\left| 22 - 10 \right|}{-2} = \frac{\left| 12 \right|}{-2} = \frac{12}{-2} = -6$

This is correct.

Checking $y = -2$:

$\frac{\left| -2 - 10 \right|}{-2} = \frac{\left| -12 \right|}{-2} = \frac{12}{-2} = -6$

This is also correct.

Conclusion:

Both $y = 22$ and $y = -2$ are valid solutions, and there are no extraneous solutions.
