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 :

                     -2*(x+7)-(9*x)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (0 -  2 • (x + 7)) -  9x  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   -11x - 14  =   -1 • (11x + 14) 

Equation at the end of step  3  :

  -11x - 14  = 0 

Step  4  :

Solving a Single Variable Equation :

 4.1      Solve  :    -11x-14 = 0 

 Add  14  to both sides of the equation : 
                      -11x = 14
Multiply both sides of the equation by (-1) :  11x = -14


Divide both sides of the equation by 11:
                     x = -14/11 = -1.273
