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 :

                     2*(7*z-7)-(14)=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   7z - 7  =   7 • (z - 1) 

Equation at the end of step  2  :

  14 • (z - 1) -  14  = 0 

Step  3  :

Pulling out like terms :

 3.1      Pull out     14 

After pulling out, we are left with :
      14 • ( 1  *  (z-1) +( (-1) ))

Equation at the end of step  3  :

  14 • (z - 2)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    14   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    z-2 = 0 

 Add  2  to both sides of the equation : 
                      z = 2
