Question 986918: -2x-(x-1)+8=0

Instead of doing it for you, I'll do one exactly like it so
you can use what I do as a model, and do yours step by step
exactly as I did:

-3x-(x-2)+14 = 0

To get rid of the parentheses in the -(x-2), since it is preceded
by a - sign we change the sign before the x and the 2 and get -x+2.
So the above becomes:

-3x-x+2+14 = 0

Now we combine -3x-x considering it to be -3x-1x and get -4x
We also combine +2+14 and get +16, so we have

-4x+16 = 0

Now we want only the -4x on the left side so we add -16 to both sides:

-4x+16 = 0
   -16   -16
------------
-4x    = -16

Now we want just x on the left side, so we divide both sides by the
coefficient of x which is -4:




x = 4

Now do yours the same way.
