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*(2*x+2)-x-2-(39)=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   2x + 2  =   2 • (x + 1) 

Equation at the end of step  2  :

  ((6 • (x + 1) -  x) -  2) -  39  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   5x - 35  =   5 • (x - 7) 

Equation at the end of step  4  :

  5 • (x - 7)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    5   =  0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation :

 5.2      Solve  :    x-7 = 0 

 Add  7  to both sides of the equation : 
                      x = 7
