Solving basic combined equations

5x - 3=22

Step  1  :Pulling out like terms :

 1.1     Pull out like factors :

   5x - 25  =   5 • (x - 5) 

Equation at the end of step  1  :Step  2  :Equations which are never true :

 2.1      Solve :    5   =  0

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

Solving a Single Variable Equation :

 2.2      Solve  :    x-5 = 0 

 Add  5  to both sides of the equation : 
                      x = 5 

One solution was found :                   x = 5

The answer should be 3%
