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 :

                     4*(2*z-8)-(16)=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   2z - 8  =   2 • (z - 4) 

Equation at the end of step  2  :

  8 • (z - 4) -  16  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   8z - 48  =   8 • (z - 6) 

Equation at the end of step  4  :

  8 • (z - 6)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    8   =  0

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

Solving a Single Variable Equation :

 5.2      Solve  :    z-6 = 0 

 Add  6  to both sides of the equation : 
                      z = 6
