Solution - Linear equations with one unknown

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  6 • (2a + 3)  = 0 

Step  2  :

Equations which are never true :

 2.1      Solve :    6   =  0

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

Solving a Single Variable Equation :

 2.2      Solve  :    2a+3 = 0 

 Subtract  3  from both sides of the equation : 
                      2a = -3
Divide both sides of the equation by 2:
                     a = -3/2 = -1.500
