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 :

                     3*(3*x+3)-5*x-4-(25)=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   3x + 3  =   3 • (x + 1) 

Equation at the end of step  2  :

  ((9 • (x + 1) -  5x) -  4) -  25  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   4x - 20  =   4 • (x - 5) 

Equation at the end of step  4  :

  4 • (x - 5)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    4   =  0

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

Solving a Single Variable Equation :

 5.2      Solve  :    x-5 = 0 

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