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 :

                     -z-6-7*z-(9*(-z-2)+6)=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   -z - 2  =   -1 • (z + 2) 

Equation at the end of step  2  :

  (-8z - 6) -  (-9 • (z + 2) +  6)  = 0 

Step  3  :

Equation at the end of step  3  :

  z + 6  = 0 

Step  4  :

Solving a Single Variable Equation :

 4.1      Solve  :    z+6 = 0 

 Subtract  6  from both sides of the equation : 
                      z = -6
