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 :

                     -12*x+2-(-9*x+5)=0 

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   -3x - 3  =   -3 • (x + 1) 

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

 2.1      Solve :    -3   =  0

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

Solving a Single Variable Equation :

 2.2      Solve  :    x+1 = 0 

 Subtract  1  from both sides of the equation : 
                      x = -1
