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+7-(6)=0 

Step by step solution :

Step  1  :

Solving a Single Variable Equation :

 1.1      Solve  :    -z+1 = 0 

 Subtract  1  from both sides of the equation : 
                      -z = -1
Multiply both sides of the equation by (-1) :  z = 1
