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*(3*x-1)-5-(75)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (4 • (3x - 1) -  5) -  75  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   12x - 84  =   12 • (x - 7) 

Equation at the end of step  3  :

  12 • (x - 7)  = 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-7 = 0 

 Add  7  to both sides of the equation : 
                      x = 7
