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 :

                     8-2*z-(5-5*z)=0 

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   3 + 3z  =   3 • (z + 1) 

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

 2.1      Solve :    3   =  0

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

Solving a Single Variable Equation :

 2.2      Solve  :    z+1 = 0 

 Subtract  1  from both sides of the equation : 
                      z = -1
