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 :

                     1-x-(9)=0 

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   -8 - x  =   -1 • (x + 8) 

Equation at the end of step  1  :

Step  2  :

Solving a Single Variable Equation :

 2.1      Solve  :    -x-8 = 0 

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