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 :

                     30*n-(45)=0 

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   30n - 45  =   15 • (2n - 3) 

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

 2.1      Solve :    15   =  0

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

Solving a Single Variable Equation :

 2.2      Solve  :    2n-3 = 0 

 Add  3  to both sides of the equation : 
                      2n = 3
Divide both sides of the equation by 2:
                     n = 3/2 = 1.500
