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*(1+6*r)-(14-r)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (0 -  3 • (6r + 1)) -  (14 - r)  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   -17r - 17  =   -17 • (r + 1) 

Equation at the end of step  3  :

  -17 • (r + 1)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    -17   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    r+1 = 0 

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