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
