Solution - Linear equations with one unknown

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   12 - 18z  =   -6 • (3z - 2) 

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

 2.1      Solve :    -6   =  0

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

Solving a Single Variable Equation :

 2.2      Solve  :    3z-2 = 0 

 Add  2  to both sides of the equation : 
                      3z = 2
Divide both sides of the equation by 3:
                     z = 2/3 = 0.667
