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*z-(9)=0 

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   -8z - 9  =   -1 • (8z + 9) 

Equation at the end of step  1  :

Step  2  :

Solving a Single Variable Equation :

 2.1      Solve  :    -8z-9 = 0 

 Add  9  to both sides of the equation : 
                      -8z = 9
Multiply both sides of the equation by (-1) :  8z = -9


Divide both sides of the equation by 8:
                     z = -9/8 = -1.125
