Your answers are absolutely correct!
abs%288m%2B4%29+=+2 Remove the bars to get:
8m%2B4+=+2 or 8m%2B4+=+-2 Subtract 4 from both sides in both equations.
8m+=+-2 or 8m+=+-6 Divide both sides by 8 in both equations.
m+=+-2%2F8 or m+=+-6%2F8 Reduce the fractions.
highlight%28m+=+-1%2F4%29 or highlight%28m+=+-3%2F4%29
