Answer:
x=-4
Step-by-step 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.
