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 :

                     24-(6*(-x-3))=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   -x - 3  =   -1 • (x + 3) 

Equation at the end of step  2  :

  24 -  -6 • (x + 3)  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   6x + 42  =   6 • (x + 7) 

Equation at the end of step  4  :

  6 • (x + 7)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    6   =  0

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

Solving a Single Variable Equation :

 5.2      Solve  :    x+7 = 0 

 Subtract  7  from both sides of the equation : 
                      x = -7
