Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 
  4*(2*x-6)-(10*x-6)=0 
 2x - 6 = 2 • (x - 3) 
 8 • (x - 3) - (10x - 6) = 0  -2x - 18 = -2 • (x + 9) 
 -2 • (x + 9) = 0 Solve :  -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation : 
 Solve : 
 x+9 = 0 
 Subtract 9 from both sides of the equation : 
   x = -9
