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*(x-6)-8*x-(-2+5*(2*x+1))=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  ((3•(x-6))-8x)-(-2+5•(2x+1))  = 0 

Step  2  :

Equation at the end of step  2  :

  (3 • (x - 6) -  8x) -  (10x + 3)  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   -15x - 21  =   -3 • (5x + 7) 

Equation at the end of step  4  :

  -3 • (5x + 7)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    -3   =  0

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

Solving a Single Variable Equation :

 5.2      Solve  :    5x+7 = 0 

 Subtract  7  from both sides of the equation : 
                      5x = -7
Divide both sides of the equation by 5:
                     x = -7/5 = -1.400
