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 :

                     9*(e+5)-(225)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  9 • (e + 5) -  225  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   9e - 180  =   9 • (e - 20) 

Equation at the end of step  3  :

  9 • (e - 20)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    9   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    e-20 = 0 

 Add  20  to both sides of the equation : 
                      e = 20
