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*(2*z-10)-(10)=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   2z - 10  =   2 • (z - 5) 

Equation at the end of step  2  :

  10 • (z - 5) -  10  = 0 

Step  3  :

Pulling out like terms :

 3.1      Pull out     10 

After pulling out, we are left with :
      10 • ( 1  *  (z-5) +( (-1) ))

Equation at the end of step  3  :

  10 • (z - 6)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    10   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    z-6 = 0 

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