Solve for x: |x| - 8 = - 5

$Solution, solve\:for\:x,\:\left|x\right|-8=-5\quad :\quad x=-3\quad \mathrm{or}\quad \:x=3$

Steps:

$\left|x\right|-8=-5$

$\mathrm{Add\:}8\mathrm{\:to\:both\:sides}, \left|x\right|-8+8=-5+8$

$\mathrm{Simplify}, \left|x\right|=3$

$|f\left(x\right)|=a\quad \Rightarrow \:f\left(x\right)=-a\quad \mathrm{or}\quad \:f\left(x\right)=a, x=-3\quad \mathrm{or}\quad \:x=3$
