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 :

                     36^3*r-(216)=0 

Step by step solution :

Step  1  :

 1.1     36 = 22•32

(36)³ = (2²•3²)³ = 2⁶ • 3⁶

Equation at the end of step  1  :

  ((26•36) • r) -  216  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   2⁶ • 3⁶r - 216  =   36 • (r - 6) 

Equation at the end of step  3  :

  36 • (r - 6)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    36   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    r-6 = 0 

 Add  6  to both sides of the equation : 
                      r = 6
