the answer is that the x = 16
i got this answer like this
-x - 4 = - 20 subtract 4 by both sides
-x = 16 add it all up
-16 - 4 = - 20
use your calculator if you think im wrong but this is the method i use and it is 100% correct

-x - 4 = - 20
-x = - 16 (-4 becomes + 4 on changing sides)
x = 16 (cancel both the minus signs)
x = 16
