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 :

                     2*(5-3*r)-(-4*r-16)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  2 • (5 - 3r) -  (-4r - 16)  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   26 - 2r  =   -2 • (r - 13) 

Equation at the end of step  3  :

  -2 • (r - 13)  = 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  :    r-13 = 0 

 Add  13  to both sides of the equation : 
                      r = 13
