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 :

                6*(3*a+1)-30-(3*(2*a-4))=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   2a - 4  =   2 • (a - 2) 

Equation at the end of step  2  :

  ((6 • (3a + 1)) -  30) -  6 • (a - 2)  = 0 

Step  3  :

Equation at the end of step  3  :

  (6 • (3a + 1) -  30) -  6 • (a - 2)  = 0 

Step  4  :

Step  5  :

Pulling out like terms :

 5.1     Pull out like factors :

   12a - 12  =   12 • (a - 1) 

Equation at the end of step  5  :

  12 • (a - 1)  = 0 

Step  6  :

Equations which are never true :

 6.1      Solve :    12   =  0

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

Solving a Single Variable Equation :

 6.2      Solve  :    a-1 = 0 

 Add  1  to both sides of the equation : 
                      a = 1
