we have

$-2\left|8-x\right|-6=-12$

Find the two possible solutions

Step 1

Find the first solution

we know that

the first solution is for the term [+(8-x)] positive

$-2[+(8-x)]-6=-12\\ -16+2x-6=-12\\2x=-12+22 \\x=10/2 \\x=5$

therefore

the first solution is

x=5

Step 2

Find the second solution

we know that

the second solution is for the term [-(8-x)] negative

$-2[-(8-x)]-6=-12\\ +16-2x-6=-12\\-2x=-12-10 \\-x=-22/2 \\x=11$

therefore

the second solution is

x=11

therefore

the answer is the option

B he is not correct he made a sign error
