Solution - Linear equations with one unknown

Rearrange:

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

                     3*x+7-2*(x+3)-(4*x-7)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  ((3x + 7) -  2 • (x + 3)) -  (4x - 7)  = 0 

Step  2  :

Equation at the end of step  2  :

  8 - 3x  = 0 

Step  3  :

Solving a Single Variable Equation :

 3.1      Solve  :    -3x+8 = 0 

 Subtract  8  from both sides of the equation : 
                      -3x = -8
Multiply both sides of the equation by (-1) :  3x = 8


Divide both sides of the equation by 3:
                     x = 8/3 = 2.667
