Answer:

Number = -1

Step-by-step explanation:

8 - x = 3(x + 4)

8 - x = 3x + 12 ( /+x / -12 on both sides)

8 - 12 - x + x = 3x + x + 12 - 12

-4 = 4x (/ divide by 4)

-4/4 = 4x/4

-1 = x

You didn't tell us much on what to do, so I just guessed you wanted it simplified. If you want a different answer, please do so tell me and I'll edit my answer to fit.
