Why some absolute value equations can have a extraneous solution?

Why some absolute value equations can have a extraneous solution?

it means that thing inside the absolute value A equals either positive B or negative B.

So  either the expression on the other side or the expression on the other side with a negative sign in front of it.

Hope this helps!

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
