Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 
 -2*x-8-(-6*x+4)=0 
 Pull out like factors :
 4x - 12 = 4 • (x - 3) 
Solve : 4 = 0
This equation has no solution.
A a non-zero constant never equals zero.
 Solve : x-3 = 0 
 Add  3 to both sides of the equation : 
   x = 3 
The answer is x=3
