Answer:
one solution
Step-by-step explanation:
-2|3x − 1| = 0?
Divide each side by -2
|3x − 1| = 0
3x-1 = ±0
Since +0 = -0 =0
3x-1 =0
There will be only one solution
Simply just convert all of them to fraction or decimal form. I'm going to do decimal for this one just because its easier. -3/4=-0.75. 2/3=0.67. -7/3=-2.33. Now you can order them from least to greatest. -2.33, -0.75, 0.5, 0.67,1.2
