    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
