Let me assume that this equation is -2 -8x = 40
It's usually best to move all the purely numerical items to one side first. Let me move the -2. Then, to do this I add 2 to both sides.
-2 - 8x +2 = -8x = 40 + 2 = 42 or -8x = 42
Now, to yield x 'by itself' let me divide both sides by -8.
(-8x)/-8 = x = 42/(-8) = -21/4 or x = -21/4
