-4 + 5x - 4 = 5x - 8, since both 4's are negative
2-12 would be -10. Since you are starting with 2 and taking away 12. Think of it as counting backwards by 12 (2, 1, 0, -1, -2, etc.).
So now be have (5x - 8) / -10. Now we simplify it by making it:
(5x/ -10) - (-8/-10)
In the first part both the numerator in the denominator can be divided by 5, so you end up with x/2 or (1/2)x
In the second part both the numerator and the denominator can be divided by -2, so you end up with 4/5.
this leaves you with
x/2 - 4/5

-4+5x-4 divided by 2-12
-4 + 5x -4 (simplify to 5x -8)
2-12 (simplify to just -10)
now you have 5x-8 over -10
