Answer:
The correct options are A, C and E.
Explanation
If a absolution equation is defined as

Then the solutions of the equation are x=a and x=-a.
A.


So,x=-3 is a solution of this equation.
B.

This equation has no solution because the value of |x| can no
be negative.
C.



So,x=-3 is a solution of this equation.
D.

This equation has no solution because the value of |-x| can no
be negative.
E.

Divide both sides by -1.


So,x=-3 is a solution of this equation.
F.

Divide both sides by -1.

This equation has no solution because the value of |x| can not be negative.
Therefore the correct options are A, C and E.
