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 :

                     -3*x-(20)=0 

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   -3x - 20  =   -1 • (3x + 20) 

Equation at the end of step  1  :

Step  2  :

Solving a Single Variable Equation :

 2.1      Solve  :    -3x-20 = 0 

 Add  20  to both sides of the equation : 
                      -3x = 20
Multiply both sides of the equation by (-1) :  3x = -20


Divide both sides of the equation by 3:
                     x = -20/3 = -6.667
