Subtract 3x on both sides: 6x-3x-9=3x-3x+4 which is 3x-9=4

Add 9 to both sides: 3x+9-9=4+9 which is 3x=13

Divide both sides by 3 to get x=13/3 or 4 1/3

Hope this helped!

Answer:

 x = 13/3 = 4.333

Step-by-step explanation:

   6*x-9-(3*x+4)=0  

Step  1  :

Solving a Single Variable Equation :

  Solve  :    3x-13 = 0  

Add  13  to both sides of the equation :  

                     3x = 13

Divide both sides of the equation by 3:

                    x = 13/3 = 4.333
