    |x+12| = 8 is the same as | x -(-12)| = 8, therefore x is either -20 or -4.

    simply, |a - b| is the distance between a and b on the real axis.

    \[|x+12|=8\] solve two equations \[x+12=8\] or \[x+12=-8\] first one gives \[x=-4\] second one gives \[x=-20\]

    \[|6-x|=10\] same as \[|x-6|=10\] solve \[x-6=10\] or \[x-6=-10\]

    convince yourself that \[|a-b|=|b-a|\] so you do not have to deal with the annoying \[|6-x|\] just change to \[|x-6|\]

    you wrote \[|6-x|=10\] i just changed it to \[|x-6|=10\]

    this one is easier. this one is \[|x|=9\] making \[x=\pm 9\]

    okay for lx+4l=3 you would make it 4+x=-3 and 4=x=3, correct?

    that last part was supposed to say 4+x=3
