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*(3-3*x)-(2*(x+3)-30)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (3 • (3 - 3x)) -  (2 • (x + 3) -  30)  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   3 - 3x  =   -3 • (x - 1) 

Equation at the end of step  3  :

  -9 • (x - 1) -  (2x - 24)  = 0 

Step  4  :

Step  5  :

Pulling out like terms :

 5.1     Pull out like factors :

   33 - 11x  =   -11 • (x - 3) 

Equation at the end of step  5  :

  -11 • (x - 3)  = 0 

Step  6  :

Equations which are never true :

 6.1      Solve :    -11   =  0

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

Solving a Single Variable Equation :

 6.2      Solve  :    x-3 = 0 

 Add  3  to both sides of the equation : 
                      x = 3
