1) |3x-1|=4
We need to solve two separate equations:
3x - 1 = 4 or 3x - 1 = -4
Solving for x in each equation, we get:
3x = 5 or 3x = -3
x = 5/3 or x = -1
So the solution set is {-1, 5/3} and it can be represented on a number line as:
```
<===o----o===(+)===o---->
-2 -1 5/3 2
```
2) 3|2-x|=-6
We first need to isolate the absolute value expression by dividing both sides by 3:
|2 - x| = -2
The absolute value of any number is always non-negative, so it can never be equal to a negative number, including -2. Therefore, the equation has no solution.
We can represent this on a number line as an empty set:
```
<===o====o====o====>
-2 -1 2
Ø
```
