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-9)-(4)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  4 • (2x - 9) -  4  = 0 

Step  2  :

Pulling out like terms :

 2.1      Pull out     4 

After pulling out, we are left with :
      4 • ( 1  *  (2x-9) +( (-1) ))

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   2x - 10  =   2 • (x - 5) 

Equation at the end of step  3  :

  8 • (x - 5)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    8   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    x-5 = 0 

 Add  5  to both sides of the equation : 
                      x = 5
