Answer:

8

Step-by-step explanation:

step 1: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 3*x-(4*x-8)=0

Step 2: Subtract  8  from both sides of the equation :  

                     -x = -8

Multiply both sides of the equation by (-1) :  x = 8

I got 20! I think that may be right?
