assuming [] for abs value
[x+2]=x-4
in this case you would work
x-4=+(x+2)
and
x-4=-(x+2)
[x+2]=[x-4]
(x-4)= x+2, no solution for this one.
(x-4)=-(x+2)
for inequality
[x-3]<[x+4]
you work the same steps, keep the <> signs
remember to switch sign when you have to multiply/divide both sides by a negative number.
