Question

Who knows how you do you this??

Answer 1

X + 2 = -x - 8

add x to both sides
x + 2 + x = -x - 8 + x
2x + 2 = -8

subtract 2 from both sides
2x + 2 - 2 = -8 - 2
2x = -10

divide both sides by 2
2x         -10
---   =    -----
 2            2

x = -5

Answer 2

Hi!
Okay, so this actually isn't too bad! (For number 5) Just add the negative x over to get 2x. Then subtract 2 over to get -10. Then divide by 2 (-5) and you're done! For the rest, do the same thing. Get the x's on one side, get the regular numbers on the other, and divide! Hope that helped!
