|-2x + 3| = 15
|-5x + -2| = 12
|8x + -2| = 10
|-4x + -1| = 33
|-8x + 1| = 57
|3x + 6| + 7 = 28
|2x + -3| + -7 = 12
|-4x + 5| + 3 = 30
2|x + -2| + -6 = -4
2|x + -5| + -3 = -1
4|-5x + -2| + -6 = 182
3|2x + -5| + 3 = 42
5|2x + 1| + -5 = 80

You can put this solution on YOUR website!
I'll do the one that's the most complicated:
4|-5x + -2| + -6 = 182
Add 6
4|-5x + -2| = 188
Divide by 4
|-5x - 2| = 47 Don't use that + -, just use minus or + (-2)
------------
Case 1:
+ (-5x - 2) = 47
-5x = 49
x = -49/5
-----------
Case 2:
- (-5x - 2) = 47
5x + 2 = 47
5x = 45
x = 9
---------------
All the other problems are similar.
I'll check your work if you send it, but no one's gonna do all those for you.
