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 :

                     x+4-(-9-3*(x-5)+8*x)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (x + 4) -  ((-9 -  3 • (x - 5)) +  8x)  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   -4x - 2  =   -2 • (2x + 1) 

Equation at the end of step  3  :

  -2 • (2x + 1)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    -2   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    2x+1 = 0 

 Subtract  1  from both sides of the equation : 
                      2x = -1
Divide both sides of the equation by 2:
                     x = -1/2 = -0.500
