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 :

                -1-7*(x+12)-(9*(1-6*x))=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (-1 -  (7 • (x + 12))) -  9 • (1 - 6x)  = 0 

Step  2  :

Equation at the end of step  2  :

  (-1 -  7 • (x + 12)) -  9 • (1 - 6x)  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   47x - 94  =   47 • (x - 2) 

Equation at the end of step  4  :

  47 • (x - 2)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    47   =  0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation :

 5.2      Solve  :    x-2 = 0 

 Add  2  to both sides of the equation : 
                      x = 2
