1(6x - 9) = (4x - 6)
ruslelena [56]

1(6x-9)=(4x-6)  

One solution was found :

                  x = 3/2 = 1.500

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    1*(6*x-9)-((4*x-6))=0  

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

2.1     Pull out like factors :

  6x - 9  =   3 • (2x - 3)  

Equation at the end of step  2  :

 3 • (2x - 3) -  (4x - 6)  = 0  

Step  3  :

Equation at the end of step  3  :

 2x - 3  = 0  

Step  4  :

Solving a Single Variable Equation :

4.1      Solve  :    2x-3 = 0  

Add  3  to both sides of the equation :  

                     2x = 3

Divide both sides of the equation by 2:

                    x = 3/2 = 1.500

One solution was found :

                  x = 3/2 = 1.500
