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 :

                     5*(3*z-6)-(15)=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   3z - 6  =   3 • (z - 2) 

Equation at the end of step  2  :

  15 • (z - 2) -  15  = 0 

Step  3  :

Pulling out like terms :

 3.1      Pull out     15 

After pulling out, we are left with :
      15 • ( 1  *  (z-2) +( (-1) ))

Equation at the end of step  3  :

  15 • (z - 3)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    15   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    z-3 = 0 

 Add  3  to both sides of the equation : 
                      z = 3
