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 :

                     8-(40*a)=0 

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   8 - 40a  =   -8 • (5a - 1) 

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

 2.1      Solve :    -8   =  0

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

Solving a Single Variable Equation :

 2.2      Solve  :    5a-1 = 0 

 Add  1  to both sides of the equation : 
                      5a = 1
Divide both sides of the equation by 5:
                     a = 1/5 = 0.200
