Solution - Linear equations with one unknown

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   36a - 16  =   4 • (9a - 4) 

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

 2.1      Solve :    4   =  0

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

Solving a Single Variable Equation :

 2.2      Solve  :    9a-4 = 0 

 Add  4  to both sides of the equation : 
                      9a = 4
Divide both sides of the equation by 9:
                     a = 4/9 = 0.444
