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 :

                     21*(2-x)+12*x-(44)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (21 • (2 - x) +  12x) -  44  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   -9x - 2  =   -1 • (9x + 2) 

Equation at the end of step  3  :

  -9x - 2  = 0 

Step  4  :

Solving a Single Variable Equation :

 4.1      Solve  :    -9x-2 = 0 

 Add  2  to both sides of the equation : 
                      -9x = 2
Multiply both sides of the equation by (-1) :  9x = -2


Divide both sides of the equation by 9:
                     x = -2/9 = -0.222
