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 :

                     144-(-12*(x+5))=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  144 -  (0 -  12 • (x + 5))  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   12x + 204  =   12 • (x + 17) 

Equation at the end of step  3  :

  12 • (x + 17)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    12   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    x+17 = 0 

 Subtract  17  from both sides of the equation : 
                      x = -17
