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 :

                     4*(2*x-3)-(8*(2*x+5))=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (4 • (2x - 3)) -  8 • (2x + 5)  = 0 

Step  2  :

Equation at the end of step  2  :

  4 • (2x - 3) -  8 • (2x + 5)  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   -8x - 52  =   -4 • (2x + 13) 

Equation at the end of step  4  :

  -4 • (2x + 13)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    -4   =  0

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

Solving a Single Variable Equation :

 5.2      Solve  :    2x+13 = 0 

 Subtract  13  from both sides of the equation : 
                      2x = -13
Divide both sides of the equation by 2:
                     x = -13/2 = -6.500
