Question

what answer is a solution to the equation |k+6|=3
A. {-3,9}
B. {-3,3}
C. {-9,-3}
D. k>_-9 and k<_-3

Answer 1

look:
|k+6|=3

so here is how to solve this: anything in absolute value is positive:

k+6=3 => k=-3
-k-6=3 => k=-9

now lets check: |-3+6|=3 => 3=3 correct!
|-9+6|=3 => 3=3 correct!

thus the roots are -3 and -9
