x=4. divide both sides by -1 to get 8=x+4, then subtract 4 from both sides.

Answer: 4

Step-by-step explanation:

because to get rid of the 4 you have to cancel it out w/ the opposite # on both sides meaning 4 - 4 = 0 while -8 - 4 = 4 and since there's a negitive sign you hav -x which means you have to divide it by -1 on both sides which gives you 4
