What happens when the absolute value in the middle of a problem has a minus sign in front of it?

If I understand your question right, you mean something that looks like this?

-|-7|

When we have solved everything we can inside an absolute value, we shift it to a positive number. If a negative symbol is in front of it AFTER the shift, then it is a negative number.

3 - |-7| = ?
The absolute value has been simplified and calculated as much as possible. Shift it.
3 - 7 = -4

If you have a variable, then that is different.

3 - |-7 + x| = 2

Subtract 3 from both sides.

-|-7 + x| = -1

What could x possibly be that would satisfy the equation? -7 + something must be -1. Try 6.

-|-7 + 6| = -1
-|-1| = -1
- 1 = -1
-1 = -1
