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 :

                     3*(4*x+2)-4*x-2-(-4)=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   4x + 2  =   2 • (2x + 1) 

Equation at the end of step  2  :

  ((6 • (2x + 1) -  4x) -  2) -  -4  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   8x + 8  =   8 • (x + 1) 

Equation at the end of step  4  :

  8 • (x + 1)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    8   =  0

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

Solving a Single Variable Equation :

 5.2      Solve  :    x+1 = 0 

 Subtract  1  from both sides of the equation : 
                      x = -1
