    x=-2

    You have to bring the unknown to one side by itself in order to solve.

    So

    8-10=x

    -2=x

    1 x=4 2 x=5 3 x=3 4 x=3 5 x=2 6 x=3 7 x=4 8 x=4 9 x=6 10 x=4 11 x=6

    This would be just like saying -x+8=10. So here we would take -8 off both sides. So now -x=2. Divide each side by -1, and get x= - 2. (x equals negative 2)

    8 - x = 10

    -8 -8

    - x = 2

    *-1 *-1

    x = -2

    Hope this helps

    Alright. explanation?

    welll. you want to isolate x, so subtract 8 from both sides.

    Then, you would get . -x=10-8 So then, -x would equal 2. -x=2

    Then. to get the negative out so the x would be by itself, you divide the -1 out, which you would get x= negative 2. ;)
