Answer:
x=-4
Explanation:
The given equation is

Subtract 3 from both sides.


Divide both sides by -2.


If |x|=a, then x=a or x=-a.

Case 1:

Subtract 1.5 from both sides.


Divide both sides by 0.5.

Case 2:

Subtract 1.5 from both sides.


Divide both sides by 0.5.

Therefore, one solution is x=-2 and other solution is x=-4.
